18)

7 paise = 0.07 rupees

7rupees 7paise = 7.07 rupees

19)

Let the angle be x.

Given, x = complement of x

We know of any angle and it's complement is 90°

So,

x + x = 90°

2x = 90°

x = 45°

Therefore, the angle is 45°

20)

In the angle,

110° is an exterior angle.

50° and x are interior angles.

We know, in a triangle,

sum of two opposite interior angles = exterior angle

50° + x = 110°

x = 60°
