Answer: 4.096 inches squared

Explanation:

Hi there,

To find the area of a triangle using SSA, you should use the formula:


A=(1)/(2) *ab*sin(angle)

With a and b representing side lengths.

It is important to note that this equation only works when the angle is sandwiched in between the two sides, so, for example, if you were given angle Q instead of angle R, then you would have to use a different formula, but in this case it works.

Your setup should look like this:


A=(1)/(2) *2.5*4*sin(55)

A=4.096 inches squared

Hope this helps, let me know if you have questions.
