The larger of two numbers is 5 more than twice the smaller. if the smaller is subtracted from the larger, the result is 12. what are the two numbers ?

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.

Which ordered pair (c,d) is a solution to the given system of linear equations- c+2d=13 -9c-4d=-15

How can you construct perpendicular lines and prove theorems about perpendicular lines
