Respuesta :

x = half of the width
2x = the full width

Because of this fact, we know that the angle 45 degrees is bisected to get 45/2 = 22.5 degrees

tan(angle) = opposite/adjacent
tan(22.5) = x/75
x = 75*tan(22.5)
x = 31.066017

Multiply both sides by 2 to get
2*x = 2*31.066017
2x = 62.132034
2x = 62.13

Answer:  62.13 inches
