Seperate the number 53 into 3 parts so that the second number is 3 less than the first number and the third number is twice the first number. give the value of the second number.

∠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°

both equations and proportions are better.
