Answer:

115 degrees

Explanation:

We know that all the angles of a triangle add up to 180 degrees.

Therefore 7x+10+x+20+2x=180

Combine like terms

10x+30=180

Subtract 30 from both sides (subtraction property of equality)

10x=150

Divide both sides by 10 (division property of equality)

x=15

Now we can plug this into the largest angles equation.

7(15)+10

= 115 Degrees.
