Question

the difference betweeb two complementar angles are 20 degree find the angles​

Answer 1

Answer:

sim of com0lementary angles is 90

let one is x and another is x+20

hence

x+x+20= 90

2x=90-20

2x=70

x=35

and x+20 = 35+20=55

Answer 2

first complementary angle =x second angle =y

equations :-

x+y=90 --------(1)

x-y=20--------(2)

subtract 1 from 2 , we get

x+y-x+y=90-20

2y=70

y=35 put value of y in 1 ,we get

x+35=90 =>x=90-35

x=55

mark it as brainiest and please like
