Answer to Problem 45E
The length x in terms of trigonometric ratios of the angle
Explanation of Solution
Given information:
The figure is provided below,
Formula used:
The trigonometric ratios for a right angle triangle are defined as,
Calculation:
Consider the provided figure and label it as,
Observe that
Now, take the triangle
Since,
Now, in
The value of tangent function is,
Therefore,
Next, in
The value of sine function is,
Therefore,
Thus, the length x in terms of trigonometric ratios of the angle
