Question

find the angle whose supplement is four times its complement​

Answer 1

Answer:

Let the angle be x

We know that supplement of an angle = 180-x

Complement =90- x

Supplement = 4(complement)

180-x =4(90-x)

180-x= 360–4x

3x =180

x=60

Hence the angle is 60

Supplement =120; Complement = 30

Answer 2

Answer:

Please make me brainlist if it helps you

Step-by-step explanation:

let complement be x

then,

supplement is 4x

we know that

x+4x = 180

5x = 180

x = 180/5

x = 36

therefore,

C = 36°

S = 36*4 = 144°
