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

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

S b = 10m \cdot \cos (110°) + 20m \cdot \cos (30°)

Next Step Convert Units

∴

S b = 10m \cdot \cos (1.9199rad) + 20m \cdot \cos (0.5236rad)

Next Step Prepare to Evaluate

∴

S b = 10 \cdot \cos (1.9199) + 20 \cdot \cos (0.5236)

Next Step Evaluate

∴

S b = 13.9003066424355m

LAST Step Rounding Answer

∴

S b = 13.9003m
