Answer:
Arc DE = 90° 
m<GAB = 82°
Arc DC = 49°
Step-by-step explanation:
Given:
m<EAF = 74°
m<EAD = right angle = 90°
Arc BG = 82°
Required:
Arc DE,
<GAB, and
Arc DC
Solution:
Recall that the central angle measure = the intercepted arc measure.
Therefore:
✔️Arc DE = m<EAD
Arc DE = 90° (Substitution)
✔️m<GAB = arc BG 
m<GAB = 82° (Substitution)
✔️Arc DC = m<CAD
Find m<CAD
m<CAD = ½(180 - m<GAB)
m<CAD = ½(180 - 82)
m<CAD = 49°
Arc DC = m<CAD
Arc DC = 49°

Answer:
None of the points is a solution
The question doesn't look logical correct, check closely
Step-by-step explanation:
With the points ; 
(1,-1)(1,−1)
The slope is = ( -1-( -1))/( 1-1)= infinity
Similarly if you do same with 
5,-7)(5,−7) ; the slope would be infinity
