Question

Two complementary angles are such that one angle is twice the other. The greater angle
among the twoangles will be
[a] 40°
[b] 70°
[c] 60°
[d] 80°​

Answer 1

Answer:

let the angle be  X

and twice the angle be 2X

X+2X =90

3X=90

X=30

TWICE THE ANGLE

2X=60

Step-by-step explanation:

Answer 2

Answer: It is 60

Step-by-step explanation:

Let one angle be x and other be 2x

We know,

Sum of complementary angles is 90°

So,

x + 2x = 90°

3x = 90°

x = (90/3)°

x = 30°

Hence the angles are :- 30°

And (2 × 30 )° = 60°

Hence the greater angle is 60°
