(X-1) squared + y squared = 36. What is the center and radius of the circle
1 answer:
Answer:
- center (1, 0)
- radius 6
Step-by-step explanation:
<u>Given</u>
(x -1)^2 +y^2 = 36
<u>Find</u>
the circle's center and radius
<u>Solution</u>
Compare the given equation to the standard form equation for a circle.
(x -h)^2 +(y -k)^2 = r^2 . . . . . . centered at (h, k) with radius r
This tells you ...
- h = 1
- k = 0
- r = √36 = 6
Your circle is centered at (1, 0) and has a radius of 6.

Option (2)
Step-by-step explanation:
Measure of angle formed by two tangents from a point outside the circleis half the difference of the measures of the intercepted arcs.
From the figure attached,
m∠C =
=
=
=
= 180 - 150
= 30°
Therefore, measure of angle C will be 30°.
Option (2) is the answer.
