Find the value of y if the image below is a kite 10 7 12 5

y=7

Step-by-step explanation:

We know the tops 2 parts of the kite have to be equal

x+3 = 15

Subtract 3 from each side

x+3-3 =15-3

x=12

We also know the bottoms have to be equal

3y-1 =2x-4

Substitute the value for x

3y-1 =2(12) -4

3y-1 =24-4

3y-1 =20

Add 1 to each side

3y-1+1 =20+1

3y = 21

Divide each side by 3

3y/3 = 21/3

y = 7
