Answer:
Google GoGeometry problem 1288 and it will have a diagram for you
1) 1
2) PA: between 2 and 3.
2) PB: Unsure about it.
A. The equation is true.
67+33=100
70+30=100
100=100 so yes, the equation is equal.
For this use the law of sines:


cross-multiply:
16×sin (J) = 11×0.97
sin(J) = 10.72/16
sin(J) = 0.67
hit the "arcsin" button on your calculator:

therefore answer B. 42 is the correct answer!!
