It’s the 3rd one hopefully this helps
Can you please give me more detail so I can help you
Answer:
x = 43.7°
Step-by-step explanation:
Reference angle (θ) = x°
Opposite side length = 43
Adjacent side length = 45
Apply the trigonometric function, TOA, which is:
Tan θ = Opp/Adj
Substitute


x = 43.7° (nearesth tenth)
Z scores are (age - mean) / std dev
= 23 - 27 / 2 = -2 and 27-27 / 2 = 0
Using the standard normal tables we find the required percentage is 47.73%
