Find the measure of the indicated angle below
Norma-Jean [14]

Answer:

The measure of x is 70\°

Step-by-step explanation:

we know that

The formula to calculate the sum of the internal angles of a polygon is equal to

S=(n-2)*180\°

where

n is the number of sides

In this problem we have

n=9\ sides

substitute

S=(9-2)*180\°=1,260\°

Find the measure of each internal angle

Divide the sum of the internal angles by the number of sides

1,260\°/9=140\°

The value of x is half the measure of internal angle

so

x=140\°/2=70\°

Help :( I suck at math
iris [78.8K]

Answer:

D

Step-by-step explanation:

For some side lengths to create a triangle, any two of the side lengths must have an added length together of less than the third leg. Otherwise, the vertices would simply not be able to be connected by the lines. In a), 3+5=8, but since it is not more, the triangle will not be able to be formed (it would basically just be a line.) In B, 7+8< 16. In C, there is the same situation as with the first example (4+15=19). Finally, in the last one, 5+7>12, and all of the side lengths work out. Therefore, the correct answer is D. Hope this helps!

Solve for x:<br> 4x – 7 = 8x + 33
Lera25 [3.4K]

Answer:

x = 10

Step-by-step explanation:

Hey there!

To solve this question we will use PEMDAS (order of operations)

4x−7=8x+33

Subtract 8x from both sides.

4x−7−8x=33

Combine 4x and −8x to get −4x.

−4x−7=33

Add 7 to both sides.

−4x=33+7

Add 33 and 7 to get 40.

−4x=40

Divide both sides by −4.

x= 40/-4

Divide 40 by −4 to get −10.

x=−10
