There is 180 degrees in a triangle. What you need to do is set up an equation and solve for x.

(7x + 10)+(x+20)+2x =180

Combine like terms:

10x + 30 = 180

Solve for x:

10x= 150; the largest angle

X=15

Plug x into the equations

7(15)+10= 115

(15) + 20 = 35

2(15)=30

Just to check your work:

115+30+35=180
