So central angles equal their opposite arcs, and arcs total 360° degrees for the whole circle. So BAC = arc BC = 115°
And arc BAC completes a circle with BC, therefore BAC = 360 - 115
BAC = 245°
Answer:
(3, 2 )
Step-by-step explanation:
Given the endpoints are (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) [
Here (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (5, 4), thus
midpoint = [0.5(1 + 5), 0.5(0 + 4) ] = (0.5(6), 0.5(4)) = (3, 2 )
32/8=4/1
21/7=3/1
First answer is 4 and the second answer is 3.
