Complete question :
A right triangle has side lengths AC = 7 inches, BC = 24 inches, and AB = 25 inches.
What are the measures of the angles in triangle ABC?
a) m∠A ≈ 46.2°, m∠B ≈ 43.8°, m∠C ≈ 90°
b) m∠A ≈ 73.0°, m∠B ≈ 17.0°, m∠C ≈ 90°
c) m∠A ≈ 73.7°, m∠B ≈ 16.3°, m∠C ≈ 90°
d) m∠A ≈ 74.4°, m∠B ≈ 15.6°, m∠C ≈ 90°
Answer:
c) m∠A ≈ 73.7°, m∠B ≈ 16.3°, m∠C ≈ 90°
Step-by-step explanation:
Given:
Length AC = 7 inches
Length BC = 24 inches
Length AB = 25 inches
Since it is a right angle triangle,
m∠C = 90°
To find the measures of the angle in ∠A and ∠B, we have :
For ∠A:
∠A = 73.7°
For ∠B:

∠B = 16.26 ≈ 16.3°
Therefore,
m∠A = 73.7°
m∠B = 16.3°
m∠C = 90°

Step-by-step explanation:
Normal Distribution
Poputation size n = 41
Population mean X = 60
Population standard deviation σ = 7
Question is: Confidence Interval 90 % ??
As Confidence Interval is 90 % then α = 10 %
And as we are dealing with a two tail test
α/2 = 0,05
We look in Z table for values for α/2 = 0,05 and find
z(α/2) = - 1,64 and z(α/2) = 1,64
Then
Confidence Interval is
X - Zα/2 * σ/√n ≤ μ ≤ X + Zα/2 * σ/√n
60 - ( 1,64 ) * 7/√41 ≤ μ ≤ 60 + ( 1,64 ) * 7/√41
60 - 1,64 * 1,09375 ≤ μ ≤ 60 + 1,64 * 1,09375
60 - 1,79375 ≤ μ ≤ 60 + 1,79375
58,21 ≤ μ ≤ 61,79
