Please helppp!!! I have this question for geometry and I can’t figure it out.

Solve one step and two step problems

The maximum distance (in nautical miles) that a radio transmitter signal can be sent is represented by the expression 1.23h√, where h is the height (in feet) above the transmitter. estimate the maximum distance x (in nautical miles) between the plane that is receiving the signal and the transmitter. round your answer to the nearest tenth.

Solve for x in the diagram shown. a) 2.7 b) 2.9 c) 3.0 d) 3.1 e) 3.2
