Question

an angle is equal to 6 degree more than third of its supplement. Find its measure.​

Answer 1

Answer:

x = 49.5°

Step-by-step explanation:

Let the angle be x°

Its supplement is (180 - x)°

According to given condition,

x = (180 - x)/3 + 6

x - 6 = (180 - x)/3

3(x - 6) = 180 - x

3x - 18 = 180 - x

3x + x = 180 + 18

4x = 198

x = 198/4

x = 49.5°
