Step-by-step explanation:
This is only the total cost per month that is why it is only 7 and 3x since the number of downloaded games is not given.

Since angle C is not 90 degrees, it's one of the acute angles
in the right triangle.
(The side adjacent to angle C ) divided by (hypotenuse)
is the cosine of angle C .
(adjacent) / (10 inches) = cos(40 degrees)
Multiply each side by (10 inches):
Adjacent side = (10 inches) x cos(40) =
(10 inches) x 0.766 =
7.66 inches (rounded)
Answer:
Change in height of the parasail after 5 minutes = 79.8 feet.
Explanation:
Change in height = Absolute value of the differences of the initial height and final height.
Initial height of parasail = 200.6 feet.
Final height parasail = 120.8 feet.
Change in height of the parasail = 200.6 - 120.8 = 79.8 feet.
Change in height of the parasail after 5 minutes = 79.8 feet.
