Question

the difference between two angle is 20 .if these angle are complimentary find the angle​

Answer 1

Answer:

Let the first angle be = x

Let the second angle be = x + 20

Complementary Angles = Sum should be 90°

ATQ

X + X + 20 = 90°

2X = 70°

X = 35°

hence first angle = 35°

second angle = 35° + 20° = 55°

Answer 2

Answer:

The angles are 55 and 35

Step-by-step explanation:

let the angles be x and y

x-y=20,     also x+y= 90 --(1)

x= 20+y

on substituting the value of x in eqn 1

20+y+y=90                  

20 +2y =90

2y=90-20

y=70/2

 =35              therefor, x=20 +35 = 55  (substituting value of y in x-y=20)
