Given that :

A church steeple casts a shadow 114 ft long, and at the same time a 8.0-ft post casts a shadow of 5.0 ft long.

A) Let the height of the steeple be h.

The equation for the situation is :

h/8 = 114/5

B) On solving the equation,

h = 182.4 ft

C) Using trigonometrical formula,

tan θ = 58°

D) Using Pythagorean theorem,

Hypotenuse² = Base² + Perpendicular²

So,

H² = (114)² + (182.4)²

Thus, H = 215.1 ft
