Long Base of Right Trapezoid given Slant Side, Short Base, and Acute Angle Solution

Follow our step by step solution on how to calculate Long Base of Right Trapezoid given Slant Side, Short Base, and Acute Angle?

FIRST Step Consider the formula
BLong=BShort+(SSlant⋅cos(∠Acute))
Next Step Substitute values of Variables
∴ BLong=15m+(11m⋅cos(65°))
Next Step Convert Units
∴ BLong=15m+(11m⋅cos(1.1345rad))
Next Step Prepare to Evaluate
∴ BLong=15+(11⋅cos(1.1345))
Next Step Evaluate
∴BLong=19.6488008791498m
LAST Step Rounding Answer
∴BLong=19.6488m
