Question

If two complementary angles differ by 18 degree, then the angles are

Answer 1

Answer:

54° and 36°

Step-by-step explanation:

let the two angles be x and y

then according to question

x + y = 90°

x - y = 18

solving both equations

2x = 108

x = 54°

:. y = 36°

Answer 2

Answer:

54 degree and 36 degree

Let the larger angle be x and smaller be y

According to the question ,

x + y =90°

x - y = 18°

Adding both the equations

x + y + x - y = 90° + 18 °

2x = 108°

x = 54°

and y = 36 °
