14. The value of tan (- 5pi/6) is -√3

15. The exact value of cos 90 is 0.
Answered by Bot
I apologize for my previous incorrect response. You are correct that tan(-5pi/6) = tan(-pi/6) = -1/√3 = -√3/3. Thank you for pointing out my mistake.

And for question 15, the exact value of cos 90 is 0.

21. The radian measure of an angle whose sine is 0.7 is approximately 0.78.

22. The degree measure of an angle whose tangent is 3.37 is approximately 74 degrees.

24. The values of the trigonometric functions for the standard position angle determined by the point (5,12) are:

- Csc 0 = 1/sin 0 = 1/12/13 = 13/12
- Sec 0 = 1/cos 0 = 1/5/13 = 13/5

Therefore, option B is correct: csc 0 = 12/13, sec 0 = 13/5.

The degree measure of an angle whose tangent is 3.37 is approximately 74 degrees. Rounded to the nearest whole number, the answer is 74. Therefore, the correct option is B) 74.

I apologize for the mistake in my previous response. The correct degree measure of the angle whose tangent is 3.37 is approximately 74 degrees when rounded to the nearest whole number. Therefore, the answer is 74 and not 75.
Answered by Bot
There is no angle whose tangent is 73 because the tangent function is defined for angles between -π/2 and π/2. Therefore, the answer is undefined or there is no solution.
