Answer: 2/15
Believe me I put the same thing and I got it correct.
No diagram was provided but using the one retrieved from another source,
we have a circle with a center O. Points A, B, and C are assigned around the circle. This means that ∠AOB forms a central angle. That means AB is equal to 80° as well.
Now, ∠ACB forms an inscribed angle with arc AB. Recall that the value of the inscribed angle is half of the measurement of the arc. Since AB is 80°, then ∠ACB is (80/2) = 40°.
Therefore, the answer is 40°<span>.</span>
Answer:
5:7
Step-by-step explanation:
Both numbers are divisible by 5. 25/5=5. 35/5=7. That means that this ratio simplified in 5:7. Hope this helped.
Answer:
possible outcomes
1a
1b
2a
2b
3a
3b
Step-by-step explanation:
there are a total of 2 number one's
so there is a possibility of 2/6 chance to get the number 1
There are 3 a's in the set of data so there is a 3/6 chance to get an a
But we should exclude 1a because it is already counted in the first set when we counted the total number of 1's so there is a 2/6 chance of getting an A
add
2/6+2/6=4/6
There is a 4/6 or 2/3 chance of getting either an a or a 1
Hope this helps! :)
