What is the measure of angle aoc? 42° 58° 66° 79°

answer: third option is correct.

step-by-step explanation:

since we have given that

measure of arc de = 50°

∠dbe = 58°

let the measure of arc ac be 'x'.

as we know that the measure of angle is half of the sum of intercepted arc .

so, it becomes,

and we know the measure of the arc is always equal to its central angle.

i.e. measure of arc ac = ∠aoc=66°

hence, third option is correct.

the radius is 2 times the diameter.

step-by-step explanation:

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
