Answer:
23.31 ft
Step-by-step explanation:
Reference angle = 47°
Opp = 25 ft
Adj = x
Apply trigonometry ratio TOA:
Tan 47 = Opp/Adj
Tan 47 = 25/x
x*Tan 47 = 25
x = 25/Tan 47
x = 23.3128772 ≈ 23.31 ft (to 2 d.p)
Answer:224
(b) 0.251
1. Standard deviation equation:
Where X is the mean of the data, and N the amount of data. Then, N=5
2. Estimate the Mean:
