For this case we must solve the following equation:

Adding 5 to both sides of the equation we have:

Different signs are subtracted and the major sign is placed.

We multiply by 3 both sides of the equation:

We divide by 4 on both sides of the equation:

Thus, the solution of the equation is

∠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°
