Question

angle which is two-thirds of its complement
​

Answer 1

one angle is 36 which is two third of its complement 54. they are complementary angles

Answer 2

Answer:

let the complement angle be x

according to the question

2/3x+x= 90

2+3/3x=90

5/3x=90

x =90*3/5

x =18*3

x =54

So,

2/3x=2/3*54

=2*18

=36

So the angels are 54 and 36

justification,

54 + 36 = 90
