Question

find the angle which is 2 by 3 of its complement​

Answer 1

Answer:

54 degrees

Step-by-step explanation:

Let the required angle be x.

The its complementary angle = 90-x

Given, x/(90-x) = 2/3

3x = 2*(90-x)

3x = 180-2x

3x+2x = 180

5x = 180

x = 180/5

x = 36 degrees.

Its complementary angle = 90-36 = 54 degrees.

Answer 2

Answer:

Two angles whose sum is 90 are complementary.

So, let one be x and other will be 2x/3

now

x+2x/3=90

5x/3=90

now,

x=270/5

=54

so other 2 multiplied by 54 divided by 3
