Question

If two complementary angle differ by 20degree. Find the measure of these angle

Answer 1

here is your Answer!

let the first angle be X
then
second angle x-20


Now, we know that complementary angle
==> 90°

So

X + X -20 = 90°

2x = 90+20

2x = 110

X = 110/2

X = 55°

second angle be
55-20 = 35°

Hope it's helpful ✌✌☺☺

Answer 2

complementary angles are sum of 90°

let one angle =x
another angle =y

sum of these should be 90°
x+y=90

so now we have two equations,

x-y=20
x+y=90
----------
2x=110
x=55°

so x-y=20
55°-y=20
y=35°
