The leaning tower of pisa in italy leans at an angle of about 84°. the figure below shows 52.1 meters from the base of the tower, the angle of elevation to the top is 50°. find the distance (b) from the base to the top of the tower.
the measure of angle c is
.

In simplified exponential notation, the expression a^2•a^-3•a 1/a 0
