A20 foot ladder rests against a building 15 feet from the floor. how far does the ladder extend from the base of the wall? what angle does the ladder make with the ground?

Distance between ladder and base of the wall is foot.

Angle of ladder make with the ground is about .

Step-by-step explanation:

From the given information,

Length of ladder = 20 foot

Height of building = 15 feet

We need to find the distance between ladder and base of the wall.

We know that wall is perpendicular to floor. It means ladder is hypotenuse.

Using Pythagoras theorem, we get

Therefore, the distance between ladder and base of the wall is foot.

In a right angle triangle,

Therefore, the angle of ladder make with the ground is about .

15 batches are the most you can make

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
