skad [1K]

Answer:

RT-ST=QS-ST, because subtracting the same quantity from two lines that have been stated to be equal.

Therefore RS=TQ

Angle R=Angle Q, because it is an isosceles triangle

Triangle AR

S is congruent to ATQ.

AT=AS

Because TAS is isosceles, angles 5 and 6 are equal.

Therefore, angles 4 and 7 are equal, because they are supplementary angles of the same angle.

And angles 1 and 3 are equal, because the other two angles in the triangle are equal.

The triangles RAT and QAS are congruent with SAS.

 1) C
 2) A
 3) D

<u><em>Explanation</em></u><span><u><em>: </em></u>
1) <u>Voluntary deductions</u> are amounts that you elect to come out of your paycheck every pay period. Federal tax is not voluntary; neither is state tax, nor Social Security. The only voluntary deduction in this list is health insurance. You are not obligated to pay for your health insurance by automatically withholding it from your check.

 2) <u>FICA</u> is the tax that goes towards Social Security and Medicare. It is involuntary, and it is deducted as a percentage of your gross (pre-withholding) pay.

 3) <u>A fixed expense</u> would be one that is the same from month to month. The only one of these expenses that would be the same amount monthly is a mortgage.</span></span>
