Question

I wasn't sure if it was 180 so I decided to post it

Answer 1

x = 25

Explanation:

`(2x+10)+(4x+20)=180^(o)`

`6x+30=180`

`6x=180-30`

`6x=150`

`x=150/6`

`x=25`

Hope this helps

Answer 2

25

Explanation:

These angles are supplementary, or add up to = 180 degrees:

(2x + 10) + (4x + 20) = 180

6x + 30 = 180

6x = 150

x = 25

Let's check our work:

2(25) + 10 = 60

4(25) + 20 = 120

60 + 120 = 180 degrees :)

Good luck!
