Answer:
x = 110°, y = 110°
Step-by-step explanation:
y = 110° ( vertical to 110° )
x = 110° ( alternate angle to y )
Interest formula: A = P(1 + rt)
Solving for r (Rate): r = (1/t)(A/P - 1)
Rate = (1/2)(2500/1800 - 1) = (1/2)(25/18 - 1) = (1/2)(7/18) = 7/36 ≈ 0.194
Rate = 0.194% per annum
4/3 x pi (3.14) x r (1.5)^3
4/3 = 1.33.
1.33 x 3.14 = 4.1762.
4.1762 x 1.5 = 6.2643.
6.2643^3 = 245.8202434
answer is 245.82.
