Answer:
x = 65
Step-by-step explanation:
Since we know the bottom line is = 180 (since it shows the top line)
The angle to the left of x is 90, which leaves x + 25 = 90
x = 65
Answer:
Hello! answer: 65 degrees
Step-by-step explanation:
That is a complementary angle with 25 therefore it will equal 90 degrees so...
90 - 25 = 65 therefore x = 65 degrees hope that helps!

What is the sum of (2n – 5m) and (n + m)?
Answer:
3n - 4m
Step-by-step explanation:
(2n-5m)+(n+m)
so we get this equation and from here, we expand the equation by removing the brackets, you should get:
2n-5m+n+m and just solve from here.
to make it easier, put the like terms together:
2n+n+m-5m
= 3n-4m
Answer:
3n - 4m
Step-by-step explanation:
(2n – 5m) and (n + m) in this case have the same value if the parentheses are removed. We end up with:
2n – 5m
n + m
-------------- Grouping like terms vertically, as shown here, may make this
addition a bit easier.
2n – 5m
n + m
--------------
3n - 4m (final answer)

10) The second angle in a triangle is 3° less than twice the first angle. The third angle measure 8° more than
twice the first angle Find each angle.
Answer:
35, 67 and 78
Step-by-step explanation:
the angles are:
n, 2n-3 and 2n+8
there are 180 degrees in a triangle, so adding those terms together will give us 180
5n + 5 = 180
180 - 5 = 175
5n = 175
175 / 5 = 35
n = 35
now we have n we can put it in to the formula we have for the angles at the start:
n = 35
2n - 3 = 67
2n + 8 = 78
so the angles are
35, 67 and 78

1 US Dollar is equal to 100 Bells
How many US Dollars in 186,000 Bells?
**please explain how you solved 100% confused lololol
Answer:
So basically you have to multiply.
Step-by-step explanation:
If one US Dollar is equal to 100 bells then how many US Dollars would you need to get to 186,000 bells?
Mk Let's use our brains here.
Let's just convert everything to bells real quick. No dollars.
100 bells times what equals 186,000?
100 x ? = 186,000
That Number is 8600
100 x 8600 = 186,000
So now that we have that number, how many US dollars is equal to 8600?
It's 86!
Because 100(bells) x 86(dollars) = 8600 bells'
So your answer is 86 dollars
Hope this helped!

Segments AB and CB are tangent to ⨀T. What is the perimeter of ABCT?
Answer:
perimeter is 46
Step-by-step explanation:
Sq(BT) = sq(AT) + Sq(AB)
Sq(17) = Sq(8) + Sq(AB)
So AB = 15
So perimeter of ABCT is 15 + 15 + 8 + 8 = 46
Segments AB and CB are tangent by the Pythagoras theorem, So the perimeter of ABCT is 46 units.
What is the perimeter?The perimeter of any given figure is the sum of the measure of boundaries of that figure.
Segments AB and CB are tangent.
By the Pythagoras theorem,
[tex](BT)^2 = (AT)^2 + (AB)^2\\(17) ^2= (8) ^2+ (AB)^2[/tex]
So AB = 15
So perimeter of ABCT
= 15 + 15 + 8 + 8
= 46

At the neighborhood playground, your friend sits on a swing and gets pulled back by you to the highest point that you can reach. When you let go, your friend rides the swing without receiving or providing additional push. Your friend travels along an arc of 14 feet on the first swing (back to front). As the swing comes backwards, the length of the arc is .80 of the previous swing. This continues: each successive arc created by swinging is .80 of the previous swing.
a. Find the length of the arc for the 5th swing (the 5th arc). Round to the thousandths place.
b. On which swing is the length of the arc first less than 1 foot?
c. Find the total distance your friend travels in all of the swings up to and including the swing in answer to letter b.

Sarah's family traveled 5 8 of the distance to her grandmother's house on Saturday. They traveled 1 3 of the remaining distance on Sunday. What fraction of the total distance to her grandmother's house was traveled on Sunday?
Answer: The fraction of the total distance to her grandmother's house was traveled on Sunday = [tex]\dfrac18[/tex]
Step-by-step explanation:
Let x be the total distance to grandmother's house .
As per given,
Distance traveled on Saturday = [tex]\dfrac58x[/tex]
Remaining distance = [tex]x-\dfrac58 x[/tex]
[tex]=\dfrac38x[/tex]
Distance traveled of Sunday = [tex]\dfrac13[/tex] of Remaining distance
= [tex]\dfrac13\times\dfrac{3}{8}x[/tex]
= [tex]\dfrac18 x[/tex]
The fraction of the total distance to her grandmother's house was traveled on Sunday = [tex]\dfrac18[/tex]

b) A prize is divided between three people
X, Y and Z. If the ratio of X's share to Y's
share is 3:1 and Y's share to Z's share
is 2:5, calculate the ratio of X's share
to Z's share.
Answer:
X : Z = 6 : 5
Step-by-step explanation:
X : Y = 3 : 1
Double both sides
X : Y = 6 : 2
Y : Z= 2 : 5
Combined
X : Y : Z = 6 : 2 : 5
Therefor
X : Z = 6 : 5
Someone please help?? Solve for angle DCE
Answer:
58 degrees
Step-by-step explanation:
By looking at the diagram we can see that angle DCE is an outside angle
There is a special relationship between the outside angle and the arcs it intercepts
The theorem states that the outside angle is equal to half the difference of the intercepted arcs
In other words [tex]outside angle= \frac{arc AC - arc BD (the difference of the arcs)}{2}[/tex]
Knowing this formula we can solve for DCE
So it would be [tex]angle DCE= \frac{238-arcDE}{2}[/tex]
Well we do not know what arcDE is
Since we are given that the other arc is 238 we can take 238 and subtract is from 360
this will give us 122
so you have angle DCE= 238-122/2
238 minus 122 is 116
Angle DCE-=116/2
Angle DCE=58 degrees
There are other ways you can do this but this is just one of them
The length of a rectangle is 4 yd longer than its width.
If the perimeter of the rectangle is 56 yd, find its length and width.
Answer: The length of the rectangle is 16 yards and the width is 12 yards.
Step-by-step explanation:
The length is 4 yds longer than the width. Let's remove that from the perimeter so that the perimeter will be as if all sides had the same length (remember there are 2 sides for length and 2 sides for width).
[tex]56-4-4\\48[/tex]
Now we made it so that the extra 4 yards are gone and all sides are equal like a square. Now we can divide by 4 to determine the length of each of the now equal sides
[tex]\frac{48}{4} =12[/tex]
So all of the sides are 12, 12, 12, and 12. To two of the sides we can add back the extra 4 yards we took out giving us sides of 12, 12, 16, and 16.
Let's add it all together and see if it makes the perimeter of 56
[tex]12+12+16+16\\24+32\\56[/tex]
It does! Since the length is 4 yds longer than the width the length is 16 and width is 12.
