Question

the angle are complementary and the larger is four time the smaller

Answer 1

Let the two complementary angles be x
sum of two complementary angles is 90
4x+x = 90
5x = 90
x = 90/5
x = 18

4*18 = 72

Therefore the two complementary angles are 18 & 72

Hope it helps u.....

Answer 2

Hey mate your and is here...
When sum of two angles is 90° then it is called
COMPLEMENTARY ANGLE.

now start the answer
let,the smaller angle be x°
then larger number be 4x°
according to question

4x°+x° = 90°
=> 5x° = 90°
=> x° = 90°÷5
=> x° = 18°
Hence, smaller angle = x°
=18°
and larger angle =4x°
=(4×18)°
= 72°
