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.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
