Angle a is 132 degrees
5x-18=3x+42
2x-18=42
2x=60
x=30
then plug 30 in the equation for angle a
5*30-18
150-18
132
Well lets set up an equation 2 problems per second yields

for every second, x.
Now if we want the problems solved, y it will be equal to this product so

Now lets plug in 60 seconds, which is 1 minute

It can solve 120 algebra problems in 1 minute.
