​

Answer 1

Answer:

None of these

Step-by-step explanation:

Complementary angles = Sum of angles 90°

Let the angles be 'x'

Then,

Ratio of angles= 7:3

The angles are : 7x , 3x

Sum of these are :

7x + 3x= 90°

10x = 90°

x = 90/10

x = 9

Then the angles are 7x = 7 × 9 = 63

3x = 3 × 9 = 27

Smaller angle is 27°

But in the options 27° is not given,

So the answer is none of these.
