Question

find the size of an angle which is four times its complementary​

Answer 1

Answer:

Let the angle be x

Then it's complement = (4x)

Step-by-step explanation:

We know that if the sum of two angles is equal to 90 ∘

then the angles are said to be complementary.

4x+x=90 ∘

⇒5x=90 ∘

⇒x=90 ∘ /5

⇒x=18 ∘

Hence, the angle = 180 ∘

and its complement = (4×18)∘ =72 ∘

∘ refers to degree

Answer 2

Answer:

Your answer is 18°
