Building

The building I focused at an angle 30°. When I moved 5 m building I focused at an angle 45°. What is the height of the building?

Correct result:

x =  6.8 m

Solution:

tan30=x/y tan45=x/(y5)  tan45=x/(x/tan305)  x=5tan(45)tan(45)tan(30)1=6.8 m



We would be very happy if you find an error in the example, spelling mistakes, or inaccuracies, and please send it to us. We thank you!
