The radio station manager will reward a free stereo to a contest winner. there are 20 black stereos, 15 white stereos, 10 red stereos, and 5 silver stereos to chose from. what is the probability that the stereo randomly selected by the contest winner is not white?

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
