Angle theta is in standard position. If (8,-15) is on the terminal ray of angle theta , find the values of the trigonometric fun
ction
1 answer:
The point (8,-15) lies in quadrant 4.
In quadrant 4, we draw a right triangle with legs 8 and -15 and hypotenuse 17. See picture.
I will use t for theta. My phone does not have the theta key.
sin t = -15/17
cos t = 8/17
tan t = -15/8
csc t = -17/15
sec t = 17/8
cot t = 8/-15
In quadrant 4, all trig functions are negative except for cosine and its reciprocal function secant.

Answer:
Tj should write 5.75 hours on her time card.
Step-by-step explanation:
We have been given, Tj worked for 5 hours and 45 minutes.
We will convert 45 minutes to hours by dividing 45 by 60 as one hour has 60 minutes.
=0.75 hours
Hence, Tj should write 5.75 hours on her time card.
