A drone

A flying drone aimed the area for an architect. He took off perpendicularly from point C to point D. He was at the height of 300 m above ABC's plane. The drone from point D pointed at a BDC angle of 43°. Calculate the distance between points C and B in meters.

Correct answer:

x =  279.7545 m

Step-by-step explanation:

CD=300 m BDC=43 DCB=90  δ=BDC rad=BDC π180 =43 3.1415926180 =0.75049  tanδ=BC/CD tanδ=x/CD  x=CD tan(δ)=300 tan(0.7505)=279.7545 m
