Answer:
theta is 78 degrees, alpha is 85 degrees
Step-by-step explanation:
use the parallel lines
alternate interior angles means that theta + 112 = 180
and since the alternate interior of the 85 degree angle is a vrtical angle of alpha, they are equal
9x – 3y – 5x + 7y + x + y
9x-5x+x -3y+7y+y
x(9-5+1) +y(-3+7+1)
5x+5y
