What the measure of AOB?

Mathematics
1 answer:
blondinia [14]3 years ago
5 0

Answer:

∠ AOB = 17.5°

Step-by-step explanation:

∠ AOB + 110 + ∠ COD = 180 ( sum of angles in straight line )

\frac{1}{3} ∠ COD + 110 + ∠ COD = 180 ( subtract 110 from both sides )

\frac{4}{3} ∠ COD = 70 ( multiply both sides by 3 to clear the fraction )

4 ∠ COD = 210 ( divide both sides by 4 )

∠ COD = 52.5°

Thus

∠ AOB = \frac{1}{3} × 52.5° = 17.5°

A bag contains 10 red marbles, 15 yellow marbles and 5 green marbles. What is the probability of drawing a red or green marble f

Probability = 

             (number of ways it can come out the way you want)
divided by
             (total number of ways it can come out).

Total number of ways to draw a marble = 30 (marbles in the bag).

Number of ways it can succeed = 15 (number of red or green ones)

Probability = 15/30 = 1/2 = 50% .
