What are the respective values of x, y, and z for parallelogram abcd?

a . 56.31°, 67.38°, 67.38°

b. 67.38°, 33.69°, 67.38°

c. 28.15°, 56.31°, 33.69°

d. 56.31°, 56.31°, 67.38°

The interior angles of triangle BCD must add up to 180 degrees, so



Angles BAD and BCD are congruent (since this is a parallelogram) so .

Also because this is a parallelogram, the triangles BCD and ACD are congruent, so angles ABD and CBD are congruent, which means .

That leads to the answer of (D)

If 2 magazines cost $12.00. And both magazine's cost was a multiple of $3.00.

$3 x $4 = $12.00

$4 x $3 = $12.00
