(x+2)^2+(y-3)^2=183 center and radius

What basic trigonometric identity would you use to verify that csc x sec x cot x = csc^(2)x

Radii ok and nl are perpendicular to om because of the radius-tangent theorem. by definition of perpendicular, angles kom and lnm are right angles. this means that triangles kom and lnm are right triangles. angle lmn is common to both right triangles, so by the triangles kom and lnm are similar.

Lines p and q intersect. find the value of b. show your work. cite any theorems you use.
