I believe the second one, double check
Answer:
Step-by-step explanation:
Formula
h = k/temp
Givens
h = 4 hours
t = 45 degrees
Solution
3 = k / 45 Multiply both sides by 45
3*45 = k
k = 135
Problem
what happens when h = 4 hours?
h = 4
k = 135
temp = ?
4 = 135 / temp Multiply both sides by temp
4temp = 135 Divide by 4
temp = 135 / 4
temp = 33.75
Note that as the time went up, the temperature came down

<h3>Answer: choice A) </h3><h3>tan(Y) = 6/7 and tan(Z) = 7/6</h3>
Recall that the tangent of an angle is equal to the ratio of the opposite over adjacent sides
tan(angle) = opposite/adjacent
For reference angle Y, the opposite side is XZ = 6 and the adjacent side is XY = 7, so,
tan(Y) = XZ/XY = 6/7
For tan(Z), things will swap. The opposite side is now XY = 7 and the adjacent side is now XZ = 6
tan(Z) = XY/XZ = 7/6
We do not use the hypotenuse sqrt(85) at all in this problem because the tangent ratio does not involve the hypotenuse.
