Answer:

I. Evaluate the largest angle when x = 15

Step-by-step explanation:

First, solve for x:

x + 8x + x + 30 = 180

10x = 180 - 30

10x = 150

x = 15

Here in the question, his friend wants to find the largest angle in triangle.

So, input x = 15 in the largest angle.

Which is, 8x = 8(15) = 120° <--- largest angle in the triangle.
