Examine parallelogram ABCD.
∠A=8x+2 and ∠B=9x+8

Please help

x=10

Step-by-step explanation:

Adjacent angles in a parallelogram are supplementary so they add to 180 degrees. So

∠A+ ∠B=180

Substitute 8x+2 in for ∠A, and 9x+8 in for ∠B

8x+2+9x+8=180

Combine like terms

8x+9x+8+2=180

17x+10=180

Subtract 10 from both sides

17x=170

Divide by 17 on both sides

x=10

Hope this helps! :)

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
