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

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

FIRST Step Consider the formula

S b = \frac{S c - S a \cdot \cos (∠B)}{\cos (∠A)}

Next Step Substitute values of Variables

∴

S b = \frac{20m - 10m \cdot \cos (40°)}{\cos (30°)}

Next Step Convert Units

∴

S b = \frac{20m - 10m \cdot \cos (0.6981rad)}{\cos (0.5236rad)}

Next Step Prepare to Evaluate

∴

S b = \frac{20 - 10 \cdot \cos (0.6981)}{\cos (0.5236)}

Next Step Evaluate

∴

S b = 14.2484914586649m

LAST Step Rounding Answer

∴

S b = 14.2485m
