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
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.
