A rectangular movie screen has side lengths of 7 meters and 9 meters. The size of a screen is determined by its diagonal. Of the choices given below what is the approximate for the size of the screen ? 11 meters
16 meters
63 meters
130 meters

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.

In the image, point a marks the center of the circle. which two lengths must form a ratio of 1 : 2? (options are in the images since thought they were harmful phrases)

If angle 2=3x +1 and angle 3=2x +4what is angle 2
