The explanation is shown below:

1. By definition, the consecutive angles of a parallelogram are sumplementary, which means that the sum is 180 degrees. And the opposite angles are congruent.

2. Based on this, you have:

(x+y)+y=180 and (2x+3)+z=180

3. and are opposite, therefore:

z=y

So:

(2x+3)+y=180

4. Solve for in the equation (x+y)+y=180 and substitute it into (2x+3)+y=180 :

$x+2y=180\\x=180-2y$

2(180-2y)+3+y=180

5. Solve for :

$360-4y+3+y=180\\-3y=180-363\\y=61\\z=61$

Mathematics

$(4.3 \times {10}^{5} )(1.6 \times {10}^{4} ) = 6.88 \times {10}^{9}$

$(2.25 \times {10}^{3} )(5.8 \times {10}^{6} ) = 13.05 \times {10}^{9} = 1.305 \times {10}^{10}$

I hope I helped you ^_^
