In ABC, you know that a = 2, b = 3 and mA = 30°. Which option below lists the number of triangles and gives the correct explanation?

There is exactly one triangle because b sin A = 0.5 b.
There are two triangles because b sin A < a < b.
There are no triangles because b sin A < a.
There are three triangles because b sin A = 0.5 b and b sin A < a < b.

Simplify a7/a4 a) 1/a3 b)-a/a2 c)a4/a3 d)a3

Plz hurry evaluate the expression a+b where a=8 and b=19
