If there’s a missing side you subtract the two know angles from 180*. Plug the two angles into the formula a+b+c=180*. i hope this helps :)
the answer is the second one, letter b. it would be (6,0) and (0,3)

Answer:
3x-120 = x - 30
2x -120 = -30
2x= 90
x= 45
3(45) -120 (plug x into angle p to check your answer)
135-120
15 degrees
45-30 (plug x into angle r to make sure it's the same thing as angle p)
15 degrees (they're equal so now figure out angle Q and answer the question)
180 - (15 +15)
180- 30
150 is the measure of angle Q
so, the triangle is an obtuse isosceles triangle
