Answer:

x=11

Explanation:

3x+28+5x+52+(2x-10)=180

8x+80+2x-10=180

10x+70=180

x=180-70/10

x=11

3x+28=61

5x+52=107

2x-10=12

HOPE IT HELPS :)

Answer:

x=11

Basic fact:

Angles in a triangle add up to 180 degrees

Explanation:

so let's gather all the information we have been given

3x+28+5x+52+2x-10

now let's add everything up

3x+5x+2x=10x

28+52-10=70

we know that 10x+70 =180

-70 from both sides

10x=110

divide by 10 to get x on its own

x=11
