Question

13. The ratio of the supplementary angle to the complementary angle of an angle is 8:3. Find
the angle.
14. Find the angle whose supplementary angle is six times its complementary angle.​

Answer 1

Answer:

Let the angle be x

It's supplementary angle=180–x

It's complementary angle=90-x

ATA

(180-x) /(90- x) =8/3

3(180-x=8(90- x)

540–3x=720–8x

8x-3x=720–540

5x=180

X=180/5=36°

It's supplementary=180–36=144

Angle :supplementary angle=36:144=1:4
