Question

Find the measure of the angle which is 10° less than four times its
supplement​

Answer 1

Answer:

38 degree

Step-by-step explanation:

Answer 2

Answer:

Let the supplement be X

Another angle = 4X - 10

A/Q,

X + (4X - 10) = 180

X + 4X - 10 = 180

5X = 190

X = 190/5

X = 38

The supplement = 38

The angle = 4 × 38 - 10

= 152 - 10

= 142

Step-by-step explanation:

The angles are 38° & 142°
