Answer:
here is ur answer
Step-by-step explanation:
difference=18 degree
sum of two complementary angles=90 degree
complementry angles are 90°
let the angles be x and y.
x-y=18°..........given-------(1)
x+y=90°.........given-------(2)
Add equation1 and equation2
x-y+x+y=90-18
(for your understanding, -y +y gets canceled.)
x+x=72°
2x=72°
x=72/2
x=36°
:x+y=90°............from equation2
36+y=90°
y=90-36
y=54°
therefore the two angles are 36°and 54°.
hope it helped
