The value of angle x is 53° for the given triangle.
<h3>What is 
angle?</h3>
An angle is the formed when two straight lines meet at one point, it is denoted by θ.
In the given isosceles triangle,
one angle is 74°,
Since, two sides of the isosceles triangle are equal, so the corresponding angles will be equal to x.
The sum of angles of a triangle = 180°
x + x + 74 = 180
2x = 106
x = 53
The required value of angle x is 53°.

Answer: 0.0010
Step-by-step explanation:
Given the following :
Population Mean(m) = 4.2 years
Sample mean (s) = 3.9
Standard deviation (sd) = 0.6
Number of samples (n) = 38
Calculate the test statistic (z) :
(sample mean - population mean) / (sd / √n)
Z = (3.9 - 4.2) / (0.6 / √38)
Z = (- 0.3) / (0.6 / 6.1644140)
Z = -0.3 / 0.0973328
Z = - 3.0822086
Z = - 3.08
From the z table :
P(Z ≤ - 3.08) = 0.0010
