Two brothers build a pyramid-shaped fort. if the fort is 8 feet wide at its base, what expression could be used to calculate the height of the fort? a) 4 sin 50° b) 4 sin50° eliminate c) 4 tan 50° d) 4 tan50°

C) 4 tan 50°.   if the base angle is 50 it can be plugged it into the trigonometric ratio.  If the width is 8, half of the width would be 4 which can create a right triangle whose side can be found using tangent.



Plug in known values.


Multiply both sides by the denominator 4


C. is the answer.

Ibelieve the answer is c
