Answer 2

Given,

There are two sets of angles are given,

Set 1 : i)70° ii)45° iii)40° iv)60°

Set 2 : i)100° ii) 90° iii)60° iv)30°

To find,

The complementary angles of the angles of Set 1.

And,the supplementary angles of the angles of Set 2.

Solution,

We know that,the sum of two complementary angles is always 90°.So,we need to subtract the given angles from 90° ,to get their complementary angles.

i) 90°-70° = 20°

ii) 90°-45° = 45°

iii) 90°-40° = 50°

iv) 90°-60° = 30°

And, similarly we know that, the sum of two supplementary angles is always 180°. So, we need to subtract the given angles from 180°,to get they are supplementary angles.

i) 180°-100° = 80°

ii) 180°- 90° = 90°

iii) 180°- 60° = 120°

iv) 180°- 30° = 150°

Hence,the complementary angles are 20°,45°,50° and 30°. And, the supplementary angles are 80°,90°,120° and 150°.
