Area of Triangle given Sides B and C and Sine of Angle A Solution

Follow our step by step solution on how to calculate Area of Triangle given Sides B and C and Sine of Angle A?

FIRST Step Consider the formula

A = \frac{S b \cdot S c}{2} \cdot (\sin (∠A))

Next Step Substitute values of Variables

∴

A = \frac{14m \cdot 20m}{2} \cdot (\sin (30°))

Next Step Convert Units

∴

A = \frac{14m \cdot 20m}{2} \cdot (\sin (0.5236rad))

Next Step Prepare to Evaluate

∴

A = \frac{14 \cdot 20}{2} \cdot (\sin (0.5236))

LAST Step Evaluate

∴

A = 70m²
