Given
Interest earned is $450
The rate of interest is R=7.5%
Time period T=2.5 years
Simple Interest is given by
Substitute values
To solve this, we'll use the trigonometric function called cosine.
The cosine of an angle -in a right triangle-, is equal to the side adjacent to the angle over the hypotenuse of the triangle.
Given the angle 41, its adjacent side is
and the hypotenuse is 55, so:
We solve for
:
The answer is 41.51.
