Answer:
107.1075 yards
Step-by-step explanation:
To solve this problem, we can imagine a triangle, where one of the angles is 55 degrees, the adjacent cathetus is 75 yards, and we want to know the opposite cathetus (the height of the center of the display, "h").
The relation between opposite and adjacent cathetus is the tangent, so:
tan(55) = h/75
tan(55) = 1.4281, so:
h/75 = 1.4281
h = 75*1.4281 = 107.1075 yards
