Find length CD first, which is the hypotenuse of the triangle.
PD = opposite
Opposite & hypotenuse = SOH or sin
Sin(27) = 15/H
x h, then ÷ sin(27)
H = 15/sin(27)
H = 33.04....
Move to triangle CDR:
15 is length opposite the angle we're after.
So far, we've got the hypotenuse (which we just found to be 33.04....) & the opposite of our triangle
Hypotenuse & opposite = SOH
Sin(x) = 15/33.04... but, to find the angle we do inverse of sin
sin-1(15/33.04...) = x
x = 27
(33.04... means I used the full numbers displayed on my calculator)
Thus, RCD is 27 degrees
Hope this helps!
Answer: It's c.
Step-by-step explanation: domain is the input or x-value, and range is the output or y-value
Point N is the image of M .
<h3>What is Perpendicular bisector?</h3>
Perpendicular lines are lines that intersect at a right (90 degrees) angle.
Given : P is a point on the perpendicular bisector, l, of MN.
To prove : PM = PN
A Reflection is a transformation in which the figure is the mirror image of the other. Every point is a mirror reflection of itself .
By the definition of reflection, point P is the image of itself ,point N is the image of M .
The line l acts as a Line of symmetry or axis of reflection.
Reflections preserve length so PM = PN.
Thus , point N is the image of M .

R = 12/2 = 6 π = 3.14
Circumference of a circle: C = 2πr
2*3.14*6
6.28*6 = 37.68 or 37.69
The last options seems reasonable
Hope that helps!
