B.(4,9) This creates a right triangle with one vertex at the origin..
using the pythagorean theorem
using the defintion of the trig functions...
all of the others can be solved in a similar fashion
does the other one also make another right triangle ?
Yes try drawing a graph. Both will be right triangles.
You can draw a reference triangle for any point in the xy plane...
always draw the perpendicular to the x-axis. The hypotenuse will always be the line segment from the origin to the point.
