brendan has $65 worth of balloons and flowers delievered to his mother. he pays the bill plus an 8.5% sales tax and an 18% tip on the total cost including tax. He also pays a $10 delievery fee that is charged after the tax and tip. How much change does he receive if he pays with two $50 bill? Round to the nearest cent

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
