Didnt people already do this one ?

Step-by-step explanation:

1. x=44

Step-by-step explanation:

For number 1, the two given angles equal each other. So set them both equal to each other,

2(x+10)=3(x-8) and solve for x from there.

For number 2, there are no given numbers, but we know angle 1 and angle 7 equal each other. So then, we know angle 3 also equals 1 and 7. Then, angle 2 is supplementary to angle 3. We then know angle 5 is also equal to 1,3,7. They intersect perfectly to prove lines a and b are parallel.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

well what did you do it matters what you did : )
