Question

Find the measure of Angle 5.

measure of angle 7 = 2x+15
measure of angle 8 = 3x

Answer 1

Angle 7 and 5 are vertical angles, so they're equal.
Angles 7 and 8 are supplementary, so they have to add up to 180.
2x + 15 + 3x = 180
Solve for x, then plug it into the expression for angle 7 to get you answer

Answer 2

I got as far as they add up to 180.

Answer 3

Can you solve that equation for x?

Answer 4

thats the problem im having. I keep coming out with different answers.

Answer 5

Sorry i accidently closed the question.

Answer 6

5x + 15 = 180
5x = 165
x = 33

Answer 7

I came up with 33 once but wasnt sure if i was correct

Answer 8

you were right. and then you'd plug it into 2x+15 to get the answer

Answer 9

so 41?

Answer 10

2(33)+15

Answer 11

Im so confuzzled

Answer 12

Multiply 2 times 33 first, then add the 15

Answer 13

So 81?

Answer 14

right
