Answer to Problem 11E
The exact values of the six trigonometric functions of the angle
The trigonometric functions are same for similar triangles.
Explanation of Solution
Given info:
Formula used:
Calculation:
Using Pythagorean theorem
For triangle 1:-
We have from the given drawing
For triangle 2:-
We have from the given drawing
Here the two triangles are similar, hence the values of trigonometric functions are same for both the triangles.
Conclusion:
Thus,the exact values of the six trigonometric functions of the angle
The trigonometric functions are same for similar triangles.
