What is the measure of ∠B?
Triangle A B C with ray A G through point C and angle measures A = 3x, B = 4x, and exterior angle B C G = 10x minus 45.
60∘60 degrees
15∘15 degrees
45∘45 degrees
105∘
Answer:
Solution given:
4x+3x=10x-45[exterior angle is equal to the sum of two opposite interior angle]
45=10x-7x
x=45/3
x=15
now.
<B=4x=4×15=60° is your answer
The required measure of ∠B is 60° for the given triangle.
What is the Exterior Angle?An exterior Angle is defined as an angle produced on the outside of a polygon by extending the sides of the polygon.
According to the shown figure, we have:
The external angle is ∠BCG = 10x - 45.
And, two interior angles as ∠A = 3x, and ∠B = 4x.
As we know that the sum of two opposite interior angles equals the exterior angle.
So, we can be written as follows:
4x + 3x = 10x - 45
45 = 10x - 7x
x = 45/3
x = 15
So, the measure of ∠B is:
∠B = 4x
∠B = 4 × 15
∠B = 60°
Thus, the required measure of ∠B is 60°.

ne positive integer is 4 less than twice another. The sum of their squares is 356. Find the integers
9514 1404 393
Answer:
16 and 10
Step-by-step explanation:
Let x and y represent the two integers.
x = 2y -4 . . . . . one is 4 less than twice another
x^2 +y^2 = 356 . . . . the sum of their squares is 356
We can solve these using substitution.
(2y -4)^2 +y^2 = 356 . . . . substitute for x
5y^2 -16y +16 = 356 . . . . simpify
5y^2 -16y -340 = 0 . . . . . put in standard form
(5y +34)(y -10) = 0 . . . . . . factor*
y = 10 . . . . . the only positive solution
x = 2(10) -4 = 16
The integers are 16 and 10.

#OrganizeLearningThe chart shows the results of 20 spins that Kristie made with a spinner.
Based on these results, what is the probability that Kristie's spinner will land on Mexico the next time?
Answer:
3 / 10
Step-by-step explanation:
The required outcome = mexico ; number of spins = 6 spins
Total possible outcomes = sum. Of all spins = (6 + 4 + 5 + 5) = 20
P(Mexico on next spin) = required outcome / Total possible outcomes
P(Mexico on next spin) = 6 / 20 = 3 / 10

Answer:
<3=105°
Step-by-step explanation:
The angle directly to the right of the 75° angle is 105°, as the angles along a straight line add to 180.
<3=105° because they are corresponding angles
Answer:
Solution given:
<3+75=180[co- interior angle]
<3=180°-75°=105°

Answer:
x=4
Step-by-step explanation:
The two angles together are complementary, which means they add up to 90 degrees
solving for x:

13.) In 1990, a radio costs $25. Now,
the radio costs $5. What is the
percent of change?
Answer:
Step-by-step explanation:
80% of 25 = 5
because 10% of 25 = 2.5
and then 10 x 8 = 80
so 2.5 x 8 = 20
25 - 20 = 5
therefore, the percentage change is 80%

A triangle has an area that is 125 m2. The measure of the base is 20 m so, h = ? m.
Answer:
12.5
Step-by-step explanation:
12.5 multiplied by 20 is 250 which you divide by 2 to get the area. it plugs in to the triangle area formula which is 1/2 base times height.
Answer:
Hello! answer: h = 12.5
Step-by-step explanation:
H = 12.5 because 12.5 x 20 = 250 then we divide by 2 and get our area 125. so h = 12.5
Determine the amplitude or period as requested. Amplitude of y = 1/2 * cos 5x
Answer:
The amplitude is [tex]\frac{1}{2} = 0.5[/tex]
Step-by-step explanation:
Trigonometric function:
A trigonometric function has the following format:
[tex]A\sin{bx}[/tex] or [tex]A\cos[bx}[/tex]
In which the amplitude is A and the period is [tex]\frac{2\pi}{b}[/tex]
Amplitude of y = 1/2 * cos 5x
The multiplier is 1/2, so this is the amplitude.

There are __________ values in the data set which are greater than or equal to 20 and less than or equal to 29. There are _____________ values in the data set which are greater than or equal to 30 and less than or equal to 39. There are ___________ values in the data set which are greater than or equal to 10 and less than or equal to 19.
Answer:
30 values ; greater than or equal to 10 and less Than or equal to 39
Step-by-step explanation:
Counting the number of leaves in the plot, we have 30 leaf values. This gives the number of dataset.
The minimum value is the number created by the combination of the least stem value and the lowest leaf value, which is 10
The maximum value is obtained from the combination of the highest stem and leaf value. The highest value is 39

Answer:
MAD would be more similar than mean
Step-by-step explanation:
Without doing any calculations, I assumed that the average value for each neighbor is different since their dot plots surround different areas. The MAD is the mean absolute deviation where it shows how distributed are the dot plots compared to the average value. In this case, I can tell that both neighborhoods having a very similar distribution of dot plots relative to their average/mean. Hope this helps!
