Answer to Problem 55HP
The sine ratio uses the opposite side and hypotenuse of the
The cosine ratio uses the adjacent side and hypotenuse of the triangle.
The tangent ratio uses the opposite and adjacent sides of the triangle.
Explanation of Solution
Given information:
The use of trigonometric ratios to find the missing length of a side of a right triangle given the measure of one acute angle and the length of one side.
Calculation:
Use the angle given and the measure of the known side to set up one of the trigonometric ratios. The sine ratio uses the opposite side and hypotenuse of the triangle.
The cosine ratio uses the adjacent side and hypotenuse of the triangle.
The tangent ratio uses the opposite and adjacent sides of the triangle.
Set up the ratio and solve for the unknown measure.
