Question

please help me fast please

Answer 1

let first angle = x
let second angle =y..
as they are complementary angle..

therefore, x+y=90°
x-y=40°


adding the both x+x+y-y=90+40
=2x=130
x=65
therefore y = 90-65
= 25..


it's best answer and correct also.
I'm sure please mark it as brainlist.

Answer 2

the sum of two complementary angles =90°
x+y=90°..................{1}
given difference of two complementary angles=40°
x-y=40°{2}
adding {1}&{2}
x+y=90°
x-y=40°
______
2x=130°
x=65°
substitute x=65° in eq......{1}
65°+y =90°
y=90°-65°
y=25°
hence the angles were 65°&25°
