Answer:
<h3>B. m∠R = 110°, m∠T = 110°, m∠U = 70°</h3>
Step-by-step explanation:
The opposite angles of the parallelogram are the same.
From the diagram;
<S = <U and <R = <T
Given
<S = 70°
Since <S = <U, hence <U = 70°
Since the sum of angles in a quadrilateral is 360 degrees, hence;
<R+<S+<T+<U = 360
Since <R = <T, then;
<Y+<S+<T+<U = 360
2<T + 70+70 = 360
2<T = 360-140
2<T = 220
<T = 220/2
<T = 110°
Since <T = <R, then < R = 110°
Hence m∠R = 110°, m∠T = 110°, m∠U = 70°. Option B is correct
Perimeter: 3w + 2L = 102 ⇒ L = -1.5w + 51
Area = w * L
= w(-1.5w + 51)
= -1.5w² + 51x
A' = -3w + 51
0 = -3w + 51
3w = 51
w = 17
Perimeter: L = -1.5w + 51 ⇒ -1.5(17) + 51 = -25.5 + 51 = 25.5
Area = width * Length
= 17 * 25.5
= 433.5
Answer: 433.5 m²
The answer is V= 12315.04
Volume of cylinder is V=πr2h
Radius is 14, 28/2 =14
Plug into the equation,
π(14)^2 (20)
14^2 = 196(20) = 3920
3920*3.14(pi) = 12315.04
