Need given a triangle with leg a = 8 and the hypotenuse c = 10, find the the length of leg b.

B= 6

Step-by-step explanation:

a^2 + b^2= c^2 hypotenuse formula

Plug in what you have

8^2 + b^2= 10^2

PEMDAS

64 +b^2= 100

combine like terms

b^2=36

divide

b=6

6

Step-by-step explanation:

The Pythagorean theorem states that

8*8+B*B=10*10

64-100=B*B

√36=B

6=B

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
