Step-by-step explanation:
I don't get the question a bit but I hope this makes sense
:)
A student was conducting a study to determine how many pagos he would need for the book he is writing. So, he found that the fol
lowing number of words fit on each type of the following papers using an 11 point font:
The student looks up the word count on his favorite book, if the book has pages that are 5.5 in. x 6.5 in. and 67,062 words how many pages is the book?

<h3>Answer: 5.5 which is choice B</h3>
Have a look at the diagram I posted below. I marked on your image to add in another angle. This angle is also 20 degrees because of congruent alternate interior angles (horizontal lines are parallel). This angle I add in is the reference angle of the triangle
opposite the reference angle is the vertical side x
adjacent to the reference angle is the horizontal side 15
We'll use the tangent rule. Make sure your calculator is in degree mode.
tan(angle) = opposite/adjacent
tan(20) = x/15
15*tan(20) = x <<-- multiply both sides by 15
x = 15*tan(20)
x = 5.45955 <<--- use calculator; this is approximate
x = 5.5 <<--- round to one decimal place
