Given a right spherical triangle whose parts are a = 82°, b = 62°, and C = 90°. What is the value of the side opposite the right angle?
A). 83°30
B). 84°45
C). 85°15
D). 86°15
sin cos c = cos a cos b
cos c = cos a cos b
cos c = cos 82° cos 62°
cos c = 0.6533781321
c= -cos 0.6533781321
c = 86°15'13.5" or 86°15'
