Question

if (3x - 58)° and (x + 38)° are supplementary angles , find x and the angles.

Answer 1

Answer: 50 degrees

Step-by-step explanation:

Sum of Supplementary angles is 180.

So 3x-58+x+38=180

4x-20=180

4x=200

x=50 degrees

Answer 2

Step-by-step explanation:

Sum of supplementary angels is 180°

3x-58+X+38=180

3x+x-58+38=180

4x-20=180

4x=180+20

4x=200

X=200/4

X=50°

3x-58. X+38

3*50-58. 50+38

150-58. 88°

92°

So the angles are 92°; 88°
