Acircular mirror has a radius of 11.5 inches. how much framing do you need to frame the mirror.

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.

Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of triangle abc is 180

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ah=4 and hc=1, find bh.
