I believe you meant: Use completing the square to determine the center and radius of the circle represented by this equation: <span>X^2+y^2-10x+6y=15
x^2 - 10x + 25 - 25 + y^2 + 6y + 9 - 9 = 15
Then:
(x-5)^2 + (y+3)^2 = 24 = 2sqrt(6)
This circle is centered at (5,-3) and has radius 2sqrt(6).</span>
Multiply both sides of your equation bye the denominator
∠Q = ∠R = 47°
answer
<span>∠R
------------------------</span>
complementary angles are angles whose measures equals 90° when added. so to find the measure of this angle, we subtract 25° from 90°. the measure of the angle is 65°.
The answer is (B) 16.67 hope it helps..
