Side C of Triangle given Two Sides and Two Angles A and B Solution

Follow our step by step solution on how to calculate Side C of Triangle given Two Sides and Two Angles A and B?

FIRST Step Consider the formula

S c = S a \cdot \cos (∠B) + S b \cdot \cos (∠A)

Next Step Substitute values of Variables

∴

S c = 10m \cdot \cos (40°) + 14m \cdot \cos (30°)

Next Step Convert Units

∴

S c = 10m \cdot \cos (0.6981rad) + 14m \cdot \cos (0.5236rad)

Next Step Prepare to Evaluate

∴

S c = 10 \cdot \cos (0.6981) + 14 \cdot \cos (0.5236)

Next Step Evaluate

∴

S c = 19.7848000841728m

LAST Step Rounding Answer

∴

S c = 19.7848m
