the ladder will make a right angle triangle with the house. The hypotenuse of the triangle is the ladder, 20 ft, and the height of the triagnle is 18 ft.

Solve for the base of the right angle triangle using pythagorean's theorem:

c=20, a=18, b=?

$b^{2}=c^{2} - a^{2}\\b^{2}=20^{2} - 18^{2}$

$b=\sqrt{72}$

$b= 8.49 ft$

round to the nearest foot,

b = 8 ft

Please Help!!! Ben drove 325 miles at a rate of 65mph. How long did it take him to drive the distance? Please answer: What do we

Kruka [31]

We know how many miles he drove and the speed that he drove. We do not know how long i took him to drive that distance.

To find the time it took, divide the distance by his speed:

325 miles / 65mph = 5 hours.
