Question

A triangle has vertices A, B, and C. The measure of A is 2x degrees. The measure of B is twice the measure of A. The measure of C is three times the measure of A. What is the value of x

Answer 1

Answer: the value of x is 15°

Step-by-step explanation:

A is 2x.  B is 2(2x), so 4x.   C is 3(2x) so 6x.

The sum of all the angles of a triangle is 180°

Set up the equation:

2x + 4x + 6x = 180

12x = 180°

x = 15°
