Question

Find the value of x, and then use that value to determine each angle measure of the triangle.

Answer 1

Explanation:

Since the sum of the angles of a triangle equal 180 degrees.

2x+5x+15+4x=180

11x+15=180

11x=165

x=15

ABC=2x=2(15)=30 degrees

BCA=4x=4(15)=60 degrees

CAB=5x+15=5(15)+15=90 degrees
