Figure abcd is a trapezoid. what are the values of x and y

360= 2x+3y+(x-12)+(y+20)

360= 3x+4y+8

352=3x+4y

352-3x=4y

88-3x/4=y

352-4y=3x

117 1/3 -4y/3=x

I'm proabably wrong, but I tried.

Answer : The value of x and y are, 64° and 50° respectively.

Step-by-step explanation :

As we know that, ABCD is a trapezium and AB || CD. So, the sum of opposite angles are 180°

Given:

and,

Given:

Thus, the value of x and y are, 64° and 50° respectively.

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
