The diagram shows a dilation with scale
factor 2. Point P is the center of dilation,
line l is the pre-image, and line m is the
image
Move P to explore how the location of P
affects the dilation.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
