Step-by-step explanation:
Answer:
55°
Step-by-step explanation:
Given that;
Lines CD and DE are tangent to circle A and intersect at point D.
and:
Arc CE measures 125 degrees. Point B lies on circle A.
There lies a diagrammatic representation below given a clear picture of what this question looks like;
If arc CE is 125°, what is the measure of ∠CDE?
SO, by using the outside angle theorem
∠CDE = 
where arc CE = 125°
we can determine CBE by subtracting it from angle of a circle = 360°
Thus, CBE = 360° - 125°
CBE = 235°
Again; ∠CDE = 
∠CDE = 
∠CDE = 
∠CDE = 55°
∴ The measure of ∠CDE = 55°
Answer:
Step-by-step explanation: so to find slope it’s y2-y1/x2-x1
Slope is 1/6
Y = 1/6x + b
Plug in one set of points to find b Idek if u need to find it but
2 = 1/6(12) + b
2 = 6 + b
2-6 = -4
Y = 1/6x -4
Answer: C. 
Step-by-step explanation:
1. You have the following equation of the parabola in Vertex form:

Where h is the x-coordinate of the vextex and k is the y-coordinate of the vextex.
2. You know that the vertex of this parabola is at (-2, 5), then, susbtitute this point into the equation. Then, you obtain:

3. Therefore, the answer is the option C.
