Question

If angles of measures (3x - 5)º and (5x - 7)º are a pair of supplementary angles, find the angles.
​

Answer 1

Answer:

The angles are 67° and 113°

Step-by-step explanation:

3x-5+5x-7=180

Or, 8x=192

Or, x=24

Put the values and you will get the answer

Answer 2

Answer:

Sum of supplementary angles = 180°

3x - 5 + 5x - 7 = 180°

8x - 12 = 180

8x = 180+12

x = 192/8

x = 24°

Angle 1 = 3x - 5

= 3*24 - 5 = 67°

Angle 2 = 5x - 7

= 5 * 24 - 7 = 113°
