Question

B. If 3x - 3 and 5x + 7° are the angle of a linear pair, find their measurement the angle
​

Answer 1

x = 22°

the angles are: 63° and 117°

Explanation:

a linear pair of angles total together to be 180°

so:

3x - 3 + 5x + 7 = 180

combune like terms:

8x = 176

divide both sides of the equation by 8:

x = 22°

the angles are: 63° and 117°
