1. quad is an isosceles trapezoid                     1. given

2. qd = ua                                                       2. statement 1

3. qu = qu                                                       3. identity

4. qa = ud                                                       4. diagonals of an isosceles trapezoid are equal.

5. triangle qua congruent to triangle auq   5. sss

6. uaq =   qdu                                                 6.corresponding parts of congruent triangles are congruent

step-by-step explanation:

investment b is an ordinary annuity with $3,909.64 in the account after one year.

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
