Answer:

y=10°

Step-by-step explanation:

Here,

→(3x+18)°=(5x-4)°

→18°+4°=5x-3x

→22°=2x

→x=11°

Also,

3(4y+3)°+5x-4°=180°[The sum of the linear pair is 180°]

12y+9°+5x-4°=180°

12y+5°+5×11°=180°

12y+5°+55°=180°

12y=180°-60°

12y=120°

y=120°/12

y=10°

Opposite angles are equal

  • 3x+18=5x-4
  • 22=2x
  • x=11

Now

linear pairs are supplementary

  • 3x+18+3(4y+3)=180
  • 3(11)+18+12y+9=180
  • 33+18+12y+9=180
  • 12y+60=180
  • 12y=120
  • y=10

Kamila [148]

I believe it would have been $347,316.95 at the time of purchase.

1.2% of 456996 is 5483.952

5483.952 \times 20 = 109679.04

So:

456996 - 109679.04 = 347316.95
