Answer:
C
Step-by-step explanation:
I haven't done this math in years but from what I remember this should be the correct answer.
Answer:
D. 70 degrees.
Step-by-step explanation:
Because the 2 triangles are similar corresponding angles are congruent.
So m < P = m< X = 66 degrees.
And since there are 180 degrees in a triangle:
m < W = 180 - (m < V + m < X)
= 180 - (44 + 66)
= 70 degrees.
<span>x^2 + y^2 + 8x – 6y + 21 = 0
x^2 + 8x +16 + y^2 -6y +9 = -21 + 16 +9
(x+4)^2 + (y-3)^2 = 4
So the radius is 2
