On a basketball court the diameter of the free throw semi- circle is 12 feet. The circumference of the half court circle
is 53.38 feet. What is the total area of the semi-circle and
the half court circle together?

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
