The steps below show the incomplete solution to find the value of x for the equation 5x − 2x − 3 = −2 + 15: step 1: 5x − 2x − 3 = −2 + 15 step 2: 5x − 2x − 3 = 13 step 3: 3x − 3 = 13 which of these is most likely the next step? (4 points) 3x = 16 3x = 10 3x = 39 3x = 3i believe it is 3x=3

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.
