find the values of x and y.

Angle CDE is 90°, so x° must also be 90°. (BDC=180°, divide by 2= 90°)
Both triangles are exactly the same so angle DBA will also be 47°. You now know two angles, 90° and 47°. Triangle = 180°, so 180-90-47= y° (43°)

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
