Solution

The correct option is B
(2X-4)⁰

We know the angle of incidence is equal to the angle of reflection. So angle between Garima and normal is $(X - 4)^{\circ}$

Since the angle of incidence is $X^{0}$ . Hence the total angle will be $X^{0}$ + $X^{0}$ - $4^{0}$ .

Suppose the angle of incidence is X0. Then angle between Shweta and Garima in terms of X0 can be represented as:

The correct option is B (2X-4)0 We know the angle of incidence is equal to the angle of reflection. So angle between Garima and normal is (X−4)∘ Since the angle of incidence is X0. Hence the total angle will be X0 + X0 - 40.
