Answer:

Step-by-step explanation:

Here, I've attached a picture of the triangle that accompanies this explanation.
cot = = =
Now view the triangle.
PS. Angle theta will have a coordinate of (-, +) because it is in quadrant II.
sin of the angle would be opposite/hypotenuse, so sin =
cos of the angle would be adjacent/hypotenuse, so cos =
tan of the angle would be opposite/adjacent, so tan =
This is hard to solve when we don't know the visual graph this question is trying to refer from
180-129= 51
angle 4 is equal to angle 12 so missing angle 12= 51°
