Question

What is the formula for the area of a triangle?

Answer 1

Answer:

$\Large \boxed{\mathrm{\bold{C} }}$

Step-by-step explanation:

We can find the area of the triangle when two sides are given and the angle in between the two sides.

$\displaystyle A=\mathrm{\frac{1}{2} bc \cdot sinA}$

b and c are the sides and A is the angle in between b and c.

Answer 2

Answer:  c. (1/2) bc sin A

Step-by-step explanation:

You can find the area of a triangle using trigonometry if you know the lengths of two sides and the measure of the included angle using the following formula:

$A=\dfrac{1}{2}ab\sin C$
