- Let the first scenario be A.
- Let the second scenario be B.
- Let the unknown time be X.
Given the following data;
- Time taken A = 9 minutes
- Number of pages A = 13 pages
- Number of pages B = 60 pages
- Time taken B = X minutes
To find how long it takes him to type and spell check 60 pages;
We would use direct proportion to express the work described and solve for the unknown variable (time).
Cross-multiplying, we have;
×
×
<em>X = 41.54 ≈ 42 minutes</em>
Therefore, it will take Fred 42 minutes to type and spell check 60 pages.

<u>Angles in a Right Triangle</u>
When the side lengths of a right triangle are known and an angle must be determined, we can use the trigonometric ratios that relate angles and sides.
The tangent ratio is defined as:
Opposite leg to angle A is 8 and adjacent leg is 7, thus:
Using the inverse tangent funcion:
Calculating:
A = 48.81°
