Question

Out of a pair of complementary angles one is two- third of the other.find the angles
A)54 & 36
B)60 & 30
C)150 & 30
D)45 & 45

Answer 1

Answer:

Option A 54& 36

Step-by-step explanation:

Let the angles be x and y

Given

x+y=90                             (1)

x=(2/3)y

Substituting it in equation (1)

(2/3)y+y=90

(5/3)y=90

y=90*(3/5)

y=54

and x=36

Hence the correct answer is Option A
