x=15, y=21

Step-by-step explanation:

6x-11 is opposite angle theorem.

a triangle is 180 degrees.

triangle 2: (6x-11)+(x+5)+81 = 180

6x-11+x+5+81=180

7x=105

x=15

triangle 1: (6x-11)+(y+14)+(4y-18)=180

substitute x = 15

6(15)-11+y+14+4y-18=180

90-11+y+14+4y-18=180

5y=105

y=21

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
