When mei solved the system of equations below she got the solution x=4, y=2 4x+3y=22 x-2y=0 without solving the system yourself can you tell her whether this solution is correct

∠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°

x = 12

y = 15

step-by-step explanation:

answer: 72: 111
