Question

Find the degree measure of an angle which is 4/5 of its supplement.

Answer 1

Let the supplement angle be x
Then, angle be (4/5) of x =4x/5

ATQ,
x+4x/5 = 180°
(5x+4x)/5 = 180°
9x = 180×5
x=(180×5)/9
x=100°

Then,
x=100°
4x/5 =(4×100)/5 =400/5 =80°

Thus,
angles are 80° & 100°

Answer 2

Answer:

80 & 100

Step-by-step explanation:

माना x

इसलिए 4/5 of x = 4x/5

हल- x+4x/5=180

(5x+4x)/5=180

9x=180×5

x= 100

100 भी हो सकता है

और

4x/5=(4×100)/5=400\5=80.
