Question

Determine all three angle measurements in Triangle XYZ that has angles that measure (2x – 15)⁰, (x – 5)⁰ and 42⁰.

Answer 1

3x+22=180
3x=168
x=56

2(56)-15=97
56-5=51


Angles are: 42, 97, and 51

Answer 2

the sum of triangle is 180°

(2x-15)+(x-5)+42°=180°

2x+x-15°-5°+42°=180°

3x+22°=180°

3x=180°-22

3x=158°

x=52.67°
