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! :)

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
