Area of circle = pi r^2 = 81pi
1/3 of circle = 81pi / 3 = 27 pi units^2
answer
B. 27 pi units^2
Answer:
m∠V = 28°
Step-by-step explanation:
In ΔUVW:
- m∠U = (9x - 8)°
- m∠V = (2x + 2)°
- m∠W = (3x + 4)°
To find the measure of angle V, first find the value of x.
<u>Interior angles of a triangle sum to 180°</u>.
⇒ m∠U + m∠V + m∠W = 180°
⇒ (9x - 8) + (2x + 2) + (3x + 4) = 180
⇒ 9x + 2x + 3x - 8 + 2 + 4 = 180
⇒ 14x - 2 = 180
⇒ 14x = 182
⇒ x = 13
<u>Substitute</u> the found value of x into the expression for angle V:
⇒ m∠V = 2(13) + 2
⇒ m∠V = 26 + 2
⇒ m∠V = 28°
Therefore, the measure of angle V is 28°.
