Find the Area of the Triangle *

14

Step-by-step explanation:

first use the pythagorean theorem to find the length of the line adjacent to 4

4^2+x^2=5^2

16+x^2=25

x^2=9

x=3

then you can use the triangle area formula to find the area of the entire triangle

4*(3+7)*1/2=4*10*1/2=20

then, we find the area of the triangle that we need to subtract from the entire triangle

4*3*1/2=6

20-6=14

all but the second one

step-by-step explanation:

cuz that one goes over 180

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
