<h3>
Answer: Approximately 119.76 meters</h3>
===================================================
Work Shown:
x = starting length of the shadow
y = height of the pole
tan(angle) = opposite/adjacent
tan(58) = y/x
1.6003345 = y/x
1.6003345x = y
x = y/1.6003345
x = (1/1.6003345)y
x = 0.62486936y
-------------------------
When the angle changes, the adjacent side gets 90 meters longer
tan(angle) = opposite/adjacent
tan(36) = y/(x+90)
0.72654253 = y/(0.62486936y+90)
0.72654253(0.62486936y+90) = y
0.453994166y + 65.3888277 = y
65.3888277 = y-0.453994166y
65.3888277 = 0.546005834y
0.546005834y = 65.3888277
y = 65.3888277/0.546005834
y = 119.758478075162
y = 119.76
The height of the pole is about 119.76 meters.

Answer:
The answer is 274
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- Cara computes the mean and variance for the set 87, 46, 90, 78, and 89. She finds the mean to be 78.
<h3>
<u>To </u><u>Find</u>;</h3>
Now,
Definition of Variance:
- Variance is the value of the squared variation of the random variable from its mean value, in probability and statistics.
So,
Thus, The variance of the sequence is 274.
