Answer:
non proportional
Step-by-step explanation:
Answer:
tan (C) = 2.05
Step-by-step explanation:
Given:
A right angled triangle CDE right angled at ∠D.
Side CD = 39
Side DE = 80
Side CE = 89
We know, from trigonometric ratios that, the tangent of any angle is equal to the ratio of the opposite side to the angle and the adjacent side of the angle.
Therefore, tangent of angle C is given as:

Plug in the given values and solve for angle C.This gives,

Therefore, the measure of tangent of angle C is 2.05.
The constant of proportionality should be 45 miles per hour, and the car should travel 135 miles in three hours.
Answer:
the answer is B. as you can see from the graph Mitchell spent about 8.00 in an hour so he spent more
