Number 1. I believe is y=2x + -3 (if wrong I am very sorry)
C.90 bc it’s a right angle
Helen has 15 nickels and 6 dimes. I hope this helps, good luck!

If you can assume That COA has 3 point on the same straight line and that BOE are three points on the same straight line then <AOE = <COB because they are vertically opposite.
Step One
Find angle BOA
<BOC + <COD + <DOE + <EOA + BOA = 360o Substitute values for angles
57 + 95 + 28 + 57 + BOA = 360 Add the left side
237 + <BOA= 360 Subtract 237
<BOA = 360 - 237
<BOA = 123
Step Two
Determine Arc BDA
These angles are all central angles. They will add to the desired arc.
BDA + BOA = 360
BDA + 123 = 360 Subtract 123 from both sides.
BDA = 360 - 123
BDA = 237 <<<<<<<<<<<< Answer
