Angle A=11x-4, Angle B = 4x-11, and Angle C=63-4x. List the sides of triangle ABC in order from shortest to longest.

A. AB, AC, BC

B. AC, AB, BC

C. BC, AB, AC

D. AB, BC, AC

1. The sum of of the interior angles of a triangle is 180°.

2. Keeping this on mind, you have:

A+B+C=180

A=11x-4

B = 4x-11

C=63-4x

3. When you substitute these values, you obtain:

A+B+C=180

11x-4+4x-11+63-4x=180

11x+48=180

11x=180-48

11x=132

x=132/11

x=12

3. Therefore:

A=11 (12) - 4

A=128°

B = 4 (12) - 11

B=37°

C=63-4 (12)

C=15°

5. The answer is:

A. AB, AC, BC
