Step-by-step explanation:
Answer:
x = 23 degrees
Because if you look at diagram x is vertical to angle FBC, and angle FEC and angle EBA are alternate interior angles so they are equal to each other, and AC is a straight line which means it equals to 180 degrees.

x = 23 degrees
The formula for the area of a semicircle is equivalent to the area if it were a circle divided by 2. Since the bottom edge of the window is 36 inches long, this means that its diameter is also 36 inches long. This gives an area of 508.94 square inches.
The solution is:
A = Acircle/2 = pi*r^2/2 = pi*(18)^2/2 = 508.94 in^2
The answer is (-1,3) and (-2,6)
