An angle is supplementary and one measures 70° what is the measurement of the other angle?
Answer:
x= 110
Step-by-step explanation:
Supplementary angles add to 180
Let x be the other angle
x +70 =180
Subtract 70 from each side
x+70-70=180-70
x = 110
Answer:
110 degrees
Step-by-step explanation:
Supplementary angles add to 180 degrees.
We have two angles: one is unknown and the other is 70 degrees.
These 2 angles added together must equal 180.
x+70=180
Since we are trying to find x, the unknown angle, we have to get x by itself. Since 70 is being added to x, subtract 70 from both sides.
x+70-70=180-70
x=110
So, the other angle is 110 degrees
WILL MARK BRAINLIEST! If you buy 3 pounds of hamburg for $8.97, how much will it cost for 5 pounds of hamburg?
Answer:
14.95
Step-by-step explanation:
every 1 pound is 2.99 so you would do 2.99 * 5
Answer:
$14.95
Step-by-step explanation:
To find the slope or the cost per pound of hamburger you divide 8.97 by 5 in order to find out it costs 2.99 per hamburger. You then, multiply 2.99 by 5 to gather that to buy 5 pounds of hamburger it would cost $14.95.

Answer:
(-1, -2.5)
Step-by-step explanation:
The midpoint formula is just basicallyadding both of the x values and then dividing the sum of them by 2, after that you will be adding both y values and then dividing them by 2, then you will get the midpoint x and y coordinate values. You can look up midpoint formula on google to see how it's actually written. You have to make sure to add correctly when you are using the negative numbers, because they can actually turn the equations into subtraction. Keep in mind, it can beconfusing sometimes when you are working with positive and negative numbers together. So make sure to just double check your work and also to make sure you added correctly.

A 10-foot ladder is to be placed Against the side of the building. The base of the latter must be placed in an angle of 72° With the level ground for a secure footing. Find, to the nearest inch, how far the base of the latter should be from the side of the building and how far up the side of the building the latter will reach.
Answer:
Distance of foot of ladder from building: 37.2 inches
Distance of top of ladder from building's base: 114 inches
Step-by-step explanation:
Please refer to the figure attached in the answer area.
A right angled triangle [tex]\triangle ABC[/tex] is formed by the ladder with the building where hypotenuse is the length of ladder.
Hypotenuse, AC = 10 foot
Also, we are given that angle made by the base of ladder with the ground is [tex]72^\circ[/tex].
We have to find AB and BC.
[tex]\angle BAC = 72^\circ[/tex]
Using trigonometric functions:
[tex]cos \theta= \dfrac{Base}{Hypotenuse}\\cos 72^\circ= \dfrac{AB}{AC}\\\Rightarrow 0.309 = \dfrac{AB}{AC}\\\Rightarrow AB = 10 \times 0.309\\$\approx$ 3.1 foot\\$\approx$ 37.2 inches[/tex]
[tex]sin \theta = \dfrac{Perpendicular}{Hypotenuse}\\\Rightarrow sin72^\circ = \dfrac{BC}{AC}\\\Rightarrow 0.95 = \dfrac{BC}{AC}\\\Rightarrow AB = 10 \times 0.95\\$\approx$ 9.5 foot\\$\approx$ 114 inches[/tex]
Distance of foot of ladder from building: 37.2 inches
Distance of top of ladder from building's base: 114 inches

Two interior angles of a triangle each measure 34°. What is the measure of the third interior angle?
A. 146°
B. 292°
C. 56°
D. 112°
Answer:
D. 112
Step-by-step explanation:
Since we know that a triangle totals 180 degrees, we can easily figure out the third angle. Since each measure 34 degrees, simply multiply by 2. You get 68 degrees. Then you do 180-68 to get 112.

What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Ted started a puzzle at 7:17 PM.
And, It completed the puzzle at 7:43 PM.
Now,
Since, Ted started a puzzle at 7:17 PM.
And, It completed the puzzle at 7:43 PM.
So, The time to complete the puzzle = 7:43 - 7 :17
= 0:26
= 26 minutes
Thus, Ted take 26 minutes to complete the puzzle.

Lena has painted 3/4 of a room.
She has used 1 1/2 gallons of
paint. How much paint will
she need for the whole room?
Answer:
2 gallons
Step-by-step explanation:
she painted 3/4 of the room already and that took 6/4 to do if you do improper fraction and a common denominator. so it is taking her double the numerator so to paint 4/4 of the room or 1 whole room it would take 2 gallons. I hope this makes sense.

What is the area of this triangle?
A. 12 square centimeters
B. 36 square centimeters
C. 16 square centimeters
D. 18 square centimeters
Answer:
A is the correct answer.
Step-by-step explanation:
The formula for the area of a triangle is A = 1/2 b x h
The base in this triangle is 6 and the height is 4 so 6 x 4 = 24.
Now we divide 24 by 2 which gives us 12 square centimeters.
Hope this helps
Answer: A. 12 square centimeters
Step-by-step explanation:
The area of a triangle is (1/2)bh because any triangle is half of a square (square formula = bh).
1/2bh --> 1/2 * 6 * 4 --> 12 square centimeters

To solve this we need to use this formula:
a(b+c)=ab+ac
5(7+3x)-12=35+15x-12=15x+23
Answer:
Step-by-step explanation:
Multiply the 5 to the 7 and 3x--> 35 + 15x -12. Then add 12 to the -12, making it 0 (inverse operations), and add 12 to the 35 making it 47 + 15x. :) Then you would simply divide the 15 by 15x (making the variable by itself). your answer for x should be 47/15. :> If I helped, please mark brainliest!!
