A man 1.83 metalls stands at a distance of 148 metalls away fromthe base of a tower he discovers that the angle of elevation of the tap of the tower is 63 calculate the height of the tower

Answer 1

148 metalls ??? Surely you mean meters ...??
and, since otherwise the man's height is irrelevant, I assume his eyes are 1.83m off the ground.

Draw a diagram. It should be clear that the height h is
(h-1.83)/148 = tan63°
so now just find h.
