1) Circle A (because A is the center)

2) A minor arc is smaller than a semicircle so EF, CBF, and DEF

3) 180 = EAD + 90 + 52

180 = EAD + 142

38° = EAD

4) angle EAF = 180 - 60, or 120° so arc EF should be 120° (I believe)

5) arc FCE is opposite of EF so 360 - 120 = 240°

Answer: Circle A, EF is a minor Arc, EAD = 45 degrees, Arc EF= 150 Degrees, and FCE = 210 I guess from the looks of the Picture.

Answer:

1. Use a compass to make arc marks which intersect above and below then connect.

2. $y=\frac{1}{3}x + 2$

Step-by-step explanation:

1. To construct a perpendicular line, use a compass to draw arc marks from one end of the segment through point P. Then repeat this again at the other end. This means at point P there will be two intersecting arc marks. Repeat the process down below with the same radius as used above. Then connect the two intersections.

2. The point slope form of a line is $(y-y_1)=m(x-x_1)$ where $x_1=-3\\y_1=1$ . We write

$(y-1)=m(x--3)\\(y-1)=m(x+3)$

Since the line is to be perpendicular to the line shown it will have the negative reciprocal to the slope of the function 3x+y =-8. To find m, rearrange the function to be y=-8-3x. The slope is -3 and the negative reciprocal will be 1/3.

$(y-1)=\frac{1}{3}(x+3)$
