Let the width of the frame = x
Let the cost of a linear foot of the frame = y
Let the inside dimension of the length of the frame = a
Let the inside dimension of the width of the frame = b.
The total length of the frame = 2*a + 4x
The total width of the frame = 2b
The total amount of the frame in feet is (2a + 4x + 2b)*y = Cost

They are corresponding angles. Corresponding angles have equal measures.
C. You would first have to divide A by Pi, then take the square root of r, in order to get r by itself.
Are u solving for x or y?
115 - 40 = 75
Because 115 is the total and your getting rid of the 40 other degrees in the 115
