F=-54+14
F= 40
Subtract the difference in age from the total:

Answer:
45
Step-by-step explanation:
Find the value of the trigonometric function of t form the given information
Cost=-8/17,terminal point of t is in quadrant 3rd in which cos<0, sin<0
Sint=-√(1-cos^2t)=-√(1-64/289)
=-√(225/289)=-15/17
Tant =sin/cos= -15/-8=15/8
Csc t=-17/15
Sect =-17/8
Cot=8/15
