The exact length of b and c are as follows:
b = 2.9 ft
c = 5.8 ft
A right triangle have one of its angle as 90 degrees. Therefore,
the exact length b and c can be found using trigonometric and Pythagoras theorem.
Therefore,
sin 60 = opposite / hypotenuse
sin 60 = 5 / c
c = 5 / sin 60
c = 5 / 0.86602540378
c = 5.77367205543
c = 5.8 ft
b² = 5.8² - 5²
b = √33.64 - 25
b = √8.64
b = 2.93938769134
b = 2.9 ft
