To write the problem that uses the cosine ratio to find the measure of an unknown angle in a
Explanation of Solution
Let us consider a right triangle of the sides 3 units, 4 units and 5 units.
In triangle XYZ,
XY is the perpendicular, YZ is the base and XZ is the hypotenuse.
The measures of the triangle are,
The cosine of angle X can be calculated by,
Rounding off to the nearest tens,
The angle is 36.9 degrees.
Conclusion:
Therefore, the measure of an unknown angle is 36.9 degrees.
