Consider the following expression and determine which statements are true

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

the answer is d.x= 90°

y= 50°

arc lm= 100°

i got this one chief

amount of apples bought =$ 2.6

amount of peaches bought =$ 1.475

amount given by you to cashier= $ 20

amount received by me= amount given by you to cashier -   [amount of apples bought +amount of peaches bought]

                                        = 20   - [1.475 + 2.6]

                                        = 20 -   [ 4.075]

                                        =   $15.925

so, change received by me = $15.925
