You know that the length of the lines are equal, therefore the value of the angles should also be equal.
Think of it this way:
The greater the angle, the greater the line and vice versa.
Hope this helps.
Answer:
6u - 15/2 inches

The z-score of the person who scored 178 on the exam is fund as 2.8.
<h3>What is defined as the normally distribution?</h3>
- The proper term for just a probability bell curve is the normal distribution.
- The mean of a normal distribution is zero, as well as the standard deviation is one. It has a skew of 0 and a kurtosis of 3.
- However all symmetrical distributions are normal, not all normal distributions are symmetrical.
- Many naturally occurring phenomena resemble the normal distribution.
- However, most pricing distributions in finance are not perfectly normal.
For the given question,
Mean μ = 150
Standard deviation σ = 10
Observed value x = 178.
The z-score is calculated as;
z = (x - μ)/σ
z = (178 - 150)/10
z = 28/10
z = 2.8
Thus, the z-score of the person who scored 178 on the exam is fund as 2.8.
