The firts thig we are going to do is create tow triangles using the angles of elevation of Paul and Jose. Since the problem is not giving us their height we'll assume that the horizontal line of sight of both of them coincide with the base of the tree.
We know that Paul is 19m from the base of the tree and its elevation angle to the top of the tree is 59°. We also know that the elevation angle of Jose and the top of the tree is 43°, but we don't know the distance between Paul of Jose, so lets label that distance as
.
Now we can build a right triangle between Paul and the tree and another one between Jose and the tree as shown in the figure. Lets use cosine to find h in Paul's trianlge:
Now we can use the law of sines to find the distance between Paul and Jose:
Now that we know the distance between Paul and Jose, the only thing left is add that distance to the distance from Paul and the base of the tree:
We can conclude that Jose is 33.9m from the base of the tree.

The percentage of this number of snacks grabbed that is greater than 29, as represented by the stem plot is calculated as: A. 16%.
<h3>How to Solve a Stem Plot?</h3>In a stem plot, each data point is represented as a stem and a leaf, for example, 42 is represented as 4 | 2 on the stem plot.
Given the stem plot for the data of the number of bite-size snacks grabbed by 32 students, the number of snacks grabbed that is greater than 29 are: 32, 32, 34, 38, and 42.
This is 5 out of the total number of the students, which is 32.
Thus, the percentage of this number of snacks grabbed that is greater than 29 would be calculated as:
5/32 × 100 = (5 × 100)/32
= 500/32
= 15.625%
Approximated to the nearest tenth, we would have 16%.
Therefore, the percentage of this number of snacks grabbed that is greater than 29, as represented by the stem plot is: A. 16%.
