What is the least common multiple (lcm) of 15 and 22?

330

Step-by-step explanation:

15= 3 and 5

22=2 and 11

3 times 5 is 15

15 times 2 is 30

30 times 11 is 330

∠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°
