First, you know that you have two supplementary angles. This means that together the angles add up to 180 degrees. So:
A + B = 180 (where A = measure of angle one, B = measure of angle two)
Second, you now that angle one is 5 more than 3 times angle two:
A = 5 + 3B
Now you can plug in the second equation into the first and solve for B:
A + B = 180
(5 + 3B) + B = 180
5 + 4B = 180
4B = 175
B = 43.75
Finally, plug this value into the first equation to find A:
A + B = 180
A + 43.75 = 180
A = 136.25
So angle A is 136.25 degrees and angle B is 43.75 degrees.
