Question

An angle is equal to 8times it's complement determine the angles

Answer 1

Hey



According to the concept of complementary angles,

x + y = 90 degree

x = 8y (given)

Substitute in first equation,

8y + y = 90

9y = 90

y = 90/9 = 10

x = 90 -10 = 80 degree.

Therefore, the two angles are 80 and 10 degree.



Hope this helps

Answer 2

Hi ,

Sum of any two angles in a plane is

equals 90° are called

Complementary angles.

Let one angle = x°

Second angle = 90 - x

according to the problem given,

x = 8(90 - x )

x = 720 - 8x

x + 8x = 720

9x = 720

x = 720 / 9

x = 80°

Therefore ,

One angle = x = 80°

Second angle = 90 - x

= 90 - 80

= 10°

I hope this helps you.
