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.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
