Answer:

Step-by-step explanation:
We have been given a circle D. Secant BE and CF intersect at point A inside D. We are asked to find the measure of arc BF.
We know that when two secants intersect inside a circle, then the measure of angle formed is half the sum of intercepting arcs.




We know that degree measure of circumference of circle is 360 degrees, so we can set an equation as:





Therefore, the measure of arc BF is 80 degrees.
Answer:
it would be: A.
Step-by-step explanation:
Answer:
-1 this equation is in slope intercept for y=mx+b. the slope is variable m, which in this case is -1. the one is always invisible in front of variable
Answer:
sorry I didn't know.........
21/50 is 42 percent of the students. You will have to find 42 percent of 350 to know. 42 percent of 350 is 147.
The second answer is right
