In a circle with a radius of 5 cm and is centered at point o angle aob intercepts arc ab. arc ab has a length of 10 cm. what is the radian measure of angle aob? a.) 2 b.) 50 c.) 2 d.) 5 only answer if you're smart, the question is worth 10 points

∠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°

correct answer:

i^31 = -i
