Question

In a triangle, the second angle is twice the measure of the first, and the third angle is three times the measure of the second.

Answer 1

Let x = the measure of the first

x + 2x + 3(2x) = 180

Answer 2

If you need to solve for the first, it's whatever x is. If you need each angle, solve for x, then input into each:

x, 2x, and 3(2x)

Answer 3
