Answer:

52.0 m

Step-by-step explanation:

The triangle formed by the flagpole, the ground and the 30° line is a right triangle, with x as the required length to be found.

Using the tangent ratio

tan30° = $\frac{opposite}{adjacent}$ = $\frac{30}{x}$ ( multiply both sides by x )

x × tan30° = 30 ( divide both sides by tan30° )

x = $\frac{30}{tan30}$ ≈ 52.0 m

Using the normal distribution, it is found that Sue will get a letter grade of B.

In a <em>normal distribution </em>with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

It measures how many standard deviations the measure is from the mean.
After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem, Sue got a grade of 0.85, hence $z = 0.85$ .

Looking at the z-table, z = 0.85 has a p-value of 0.8023, hence she is approximately in the top 20%, which is below the top 15% but above the top 50%, hence she got a letter grade of B.
