Answer:
To find angle y you subtract the two angles form 180 degrees because it is a straight line. Then you subtract angle y and 72 from 180 because a triangle adds up to 180 degrees and you get angle x.

The answer is -8 because 2 negatives next to each other change to a positive
If you would like to solve the equation x^2 + 9x - 22 = 0, you can do this using the following steps:
<span>x^2 + 9x - 22 = 0
</span>(x - 2) * (x + 11) = 0
1. x = 2
2. x = - 11
The correct result would be x = 2 and x = - 11.
