Step-by-step explanation:
The interior angles of a triangle add up to 180. We know from the photo that there is a 90° angle and an 18° angle, and 90-18 is 72, so the other interior angle is 72°. The question is asking you to find the value of side x, so you'll need to use sin.
sin (72°) = x/16
x ≈ 15.2
It’s not exactly equal to one, but in many cases in math they ask for a rounded answer.
I would assume you would do base*width*weight to get your area.
