F(x) = 5x - 2
f(-3/5) = 5(-3/5) - 2
f(-3/5) = -15/5 - 2
f(-3/5) = -3 - 2
f(-3/5) = -5
Well, think of the dragonfly's speed as a ratio of miles/hours, thus making it 36/1 (as a fraction). Now to solve this, set the known ratio equal to the ratio you want to find and solve for the missing variable (x) which is hours. Cross multiply to find your (x) hours.

Answer:
sin A = 40/41
tan A = 40/9
cos A = 9/41
Step-by-step explanation:
sin theta = opp/ hyp
tan theta = opp/ adj
cos theta = adj/ hyp
We want to find the measures for angle A
sin A = 40/41
tan A = 40/9
cos A = 9/41
