An electrician cuts a 136 ft long piece of cable. one piece is 16 feet less than 3 times the length of the other piece. find the length of each piece.

∠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°

its 4 because 2 times 2 is 4, if you double the number two you get four
