what is the formula for the area of a triangle?

a. a^2 + b^2 = c^2
b. A= 1/2acosB
c. A= 1/2bcsinA
d. a^2 = sin^2 + cos^2c

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:

[tex]A=\dfrac{1}{2}ab\sin C[/tex]

Answer:

[tex]\Large \boxed{\mathrm{\bold{C} }}[/tex]

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.

[tex]\displaystyle A=\mathrm{\frac{1}{2} bc \cdot sinA}[/tex]

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