Answer:
C=8
Step-by-step explanation:
6c-9d=111
<u>-) 5c-9d=103</u>
6c-5c=c
-9c+9c=0
111-103=8
(Negative+Negative=Positive)
C=8

Answer:
The area of the park is calculated through the equation,
A = 0.5ab(cos C)
Substituting the given above,
A = 0.5(533 ft)(525 ft)(cos 53°)
A = 84201.44 ft²
2. We find the radius of the second figure by the equation,
r = C / 2π
Substituting,
r = (30 in) / (2π) = 4.77 in
The radius of the first one is 9 inches. Getting the difference of these two figures will give us an answer of 4.225 inches.

Diameter of the basketball rim = 18 inches
Circumference of the basketball = 30 inches
You would have to fin the area so= pi*r^2
Basketball rim = 3.14 * (18/2)^2 = 3.14 * 9^2 = 3.14 * 81 = 254.34 in^2
The find the Circumference so= 2*pi*r
30 = 2*3.14*r
r = 30 / (2*3.14) = 30 / 6.28 = 4.78 inches
basketball = 3.14 * (4.78)^2 = 3.14 * 22.85 = 71.75 in^2
254.34 - 71.75 = 182.59 in^

Step-by-step explanation:
Rotation by -90° about the origin is the transformation ...
(x, y) ⇒ (y, -x)
So, your pre-image points are ...
A'(6, 3) ⇒ A(3, -6)
B'(-2, 1) ⇒ B(1, 2)
C'(1, 7) ⇒ C(7, -1)
