In ΔWXY, if m∠W is five less than three times m∠Y and m∠X is 8 more than m∠W, find the measures of each angles?

yulyashka [42]

Answer:

∡W = 73°

∡X = 81°

∡Y = 26°

Step-by-step explanation:

let 'y' = measure angle Y

let '3y - 5' = measure of angle W

let '3y + 3' = measure of angle X

add all together and set equal to 180

y + 3y + 3y - 2 = 180

7y = 182

y = 26

substitute 26 for y in '3y+3' to find measure of angle X

substitute 26 for y in '3y-5' to find measure of angle W

Volume of a Sphere Formula: $\displaystyle V = \frac{4}{3} \pi r^3$

V is volume
r is radius

Step-by-step explanation:

Step 1: Define

Radius r = 9 ft

Step 2: Solve for V

Substitute in r [Volume of a Sphere Formula]: $\displaystyle V = \frac{4}{3} \pi (9 \ ft)^3$
[Volume] Evaluate exponents: $\displaystyle V = \frac{4}{3} \pi (729 \ ft^3)$
[Volume] Multiply: $\displaystyle V = 972 \pi \ ft^3$
