Question

The angles of a triangle are in the ratio of 2:3:4. What is the degree measure of the largest angle?

Answer 1

2x + 3x + 4x = 180.

Where 180 degrees is the sum of all the angles of a triangle.

9x = 180

Therefore, x = 20.

Now, what's the largest angle?

Answer 2

A) 40, B) 80, C) 90, D) 120, E) 150
