Question

Find the measure of each angle:
m<9 = 2x - 4
m<10 = 2x + 4

They are supplementary angles. I'm lost.

Answer 1

Here's what I got:
m<9 + m<10 = 180
m<9 + 2x + 4 = 180
m<9 + 2x = 176
I'm not sure what to do next.

Answer 2

rewrite m<9 as 2x - 4

Answer 3

so you'll have

2x - 4 + 2x = 176

Answer 4

so next step is to solve for x

Answer 5

wait. let me figure it out

Answer 6

sure

Answer 7

where'd you get the + 2x?

Answer 8

from what you wrote

Answer 9

m<9 + 2x = 176

Answer 10

i just rewrote m<9 as 2x - 4

Answer 11

is it 44?

Answer 12

are we talking about the value of x?

Answer 13

2x - 4 + 2x = 176

add 4 to both sides

2x + 2x = 180

combine like terms

4x = 180

divide both sides by 4

x should be 45

Answer 14

right?

Answer 15

wait lol i got confused. can we start at the beginning? "_"

Answer 16

sorry i have to leave

Answer 17

aight but ur process is right, right?

Answer 18

right

Answer 19

right. k lol

Answer 20

once you find x just substitute x into 2x - 4 and 2x + 4

Answer 21

oki thanks
