3(2)-18=-12
6-18 = -12
-12 = -12
Answer:
x=75
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 =
1. 3x-6+2x+108+88=360
5x=170
x=34
2. figure B
