In a certain chemical, the ratio of zinc to copper is 3 to 17 . A jar of the chemical contains 833 of copper. How many grams of zinc does it c

∠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°

the value of x is 28.2

0.4 liters = 400 milliliters (multiply the volume value by 1000 and it give you the answer). hope this ! ^-^
