Find the area of an oblique triangle

The video tutorial explains how to calculate the area of a triangle using trigonometry. It introduces the formula 1/2 * b * c * sin(A) and provides a step-by-step guide to perform the calculation. The tutorial emphasizes the importance of using a calculator in degree mode and concludes with rounding the result and discussing appropriate units for area measurement.

What is the formula for calculating the area of a triangle when given two sides and the included angle?

• a^2 + b^2 = c^2

• base * height

• 1/2 * a * b * sin(C)

• 1/2 * base * height

If angle A is given, which sides are used in the formula to calculate the area of the triangle?

• Any two sides

• Sides a and b

• Sides b and c

• Sides a and c

What should you ensure about your calculator when performing trigonometric calculations?

• It is in standard mode

• It is in scientific mode

• It is in degree mode

• It is in radian mode

What is the approximate area of the triangle when calculated using the given values?

• 33337.681 units

• 333.37681 square units

• 33337.681 square units

• 333.37681 units

Why is it important to include units when stating the area of a triangle?

• To show the calculation method

• To ensure clarity in the measurement

• To indicate the type of triangle

• To specify the measurement system
