Sum of all three angles of a triangle must be equal 180.
Let's add all the the angles of the given choices to get the correct answer.
A: 45+60+75=180
Sum of 45°,60°, and 75° is 180°. So, A is the correct answer.

Step-by-step explanation:
So first, you find the area of a rectangle, which would be 15 * 30 = 450. Next, find the area of the semicircle by doing
(you have to divide by 2 because it's only have a circle).
The radius is half of 15, so 15 / 2 = 7.5. This would be:




The last step is to add 450 + 88.3125 = about 538.3 m^2
