What is the value of x in the equation
x-2/3 + 1/6 =5/6

x = 4/3.

Step-by-step explanation:

x-2/3 + 1/6 =5/6

Add 2/3 and subtract 1/6 from both sides:

x - 2/3 + 2/3 + 1/6 - 1/6 = 5/6 + 2/3 - 1/6

x = 5/6 + 2/3 - 1/6

x = 5/6 + 4/6 - 1/6

x = 8/6 = 4/3.

sorry i dont know my friend

∠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°
