For question 1 and 2, complete the 2 column proof by applying the missing information for each corresponding location. I WILL GIVE BRAINILY FOR THIS I REALLY NEED HELP

Circle d circumscribes abc and abe. which statements about the triangles are true? statement i: the perpendicular bisectors of abc intersect at the same point as those of abe. statement ii: the distance from c to d is the same as the distance from d to e. statement iii: bisects cde. statement iv: the angle bisectors of abc intersect at the same point as those of abe. a. i only b. i and ii c. ii and iv d. i and iii e. iii and iv

The equation of a parabola is given. y=18x2+4x+20 what are the coordinates of the focus of the parabola?

Which equation can be solved to find one of the missing side lengths in the triangle? cos(60o) = cos(60o) = cos(60o) = cos(60o) = mark this and return
