We have a triangle, when:
hypotenuse=slant height=20 ft
opposite side=height of the tree=?
angle formed by the tree with the ground=72º


sin Ф=opposite/ hypotenuse    ⇒ opposite=(hypotenuse)(sin Ф)

In this case:
oppssite=20 ft /sin 72º=19.021...≈19

Answer: the heigth of the tree is 19 ft.

Vehicle A has a 22-gallon fuel tank and averages 20 miles per gallon. Vehicle B has a 16.7-gallon fuel tank and averages 30 mile
grin007 [14]

Both vehicles will never have the same amount of fuel in their tanks

<h3>In how many miles will both vehicles have the same amount of fuel in their tanks?​</h3>

The given parameters are:

Vehicle A

Initial = 22-gallon

Rate = 20 miles per gallon

Vehicle B

Initial = 16.7-gallon

Rate = 30 miles per gallon

The equation of each vehicle is represented as;

Fuel = Initial - Rate * Number of miles

So, we have

y = 22 - 20x --- A

y = 16.7 - 30x --- B

Substitute y = 16.7 - 30x in y = 22 - 20x

16.7 - 30x = 22 - 20x

Collect the like terms

30x - 20x = 16.7 - 22

Evaluate the difference

10x = -5.3

Divide by 10

x = -0.53

Distance cannot be negative

Hence, both vehicles will never have the same amount of fuel in their tanks
