In addition to the facts in the diagram, which statement is necessary to prove that the two triangles are congruent by the sas criterion?
a. ac = de
b. m2bac =mzfde
c. bc = ef
d. m_cab=mzedf

22 dimes and 9 nickels

step-by-step explanation:

x = 3 ± √(5+y)

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
