Find each difference. if you get stuck consider using a numberline a.9 - 4. e. -9 - 4
b.4 - 9. f. 4 - (-9)
c.9 - (-4) g. -4 - (-9)
d. -9 - (-4) h. -4 - 9

a,5. e,-13

b,-5. f,13

c,13. g,5

d,5. h,-13

Step-by-step explanation:

this is the answer

∠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°
