Question

The figure shows the dimensions of the side panel of a skateboard ramp.

Answer 1

Answer:

$A=28.7\ ft^{2}$

Step-by-step explanation:

we know that

The formula to calculate the area of a triangle applying the law of sines is equal to

$A=\frac{1}{2}(a)(b)sin(C)$

we have

$a=14\ ft$

$b=12\ ft$

$C=20\°$

substitute in the formula

$A=\frac{1}{2}(14)(12)sin(20\°)$

$A=28.7\ ft^{2}$
