Call the number of trumpet players "T" and the number of horn players "H".
We can use the given information to set up equations:
1."<span>the number of trumpet players is 4 times the number of French horn players"

2. "</span><span>There are 35 trumpet and French horn players in the band."

If you were asked to solve you could now do it by substitution:

I think is this hopefully this helps
You can use the measure of 112 on the similar shape to find b, as they are same side exterior angles. From there, you can find both a and c, because a/b and b/c are supplementary angles.
a = 68 degrees
c = 68 degrees
<span>you have to take arctan(0) to find the value of theta.
tan^-1 (x)=theta </span>
The third data table accurately represents data in the histogram.
If you draw the histogram, it looks like in the .jpeg image enclosed with this answer.
