Solution

The correct option is B
(2X-4)⁰

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

Sushweta has to send a laser signal to Garima. But she finds out that the signal misses Garima by 40. 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 Since the angle of incidence is X0. Hence the total angle will be X0 + X0 - 40.
