Answer quick helllpp solve. 7 ( n + 4 ) = 21 a. n = 10 b. n = 7 c. n = -1 d. n = 1

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.

Find the length of cu, the triangles are similar.

Acircle has a radius of 5/6 units and is centered at (3.6, 7.8) write the equation of this circle
