ZAOC measures 150°. OC is 20° clockwise from the negative x-axis, as shown. If ZAOC is rotated 60° counterclockwise, what angle does OC make with the x-axis?

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to

pls mark as brainliest

what are you trying to solve here

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
