To be parallel with that line the equation has to have the same slope as the equation given, like y = 10x + 3.
Answer:
C: 12.5
Step-by-step explanation:
The sides x and 11 could be defined as the Adjacent angle and the Hypotenuse. This means that we will use the cos function to solve this.
First we can set up our equation

Next we can solve for x by multiplying by x and dividing by 

I think it's the third one cause the 3 will b "out of the house" while the 4 will b the power.
Polygons are closed figures so any figure that is not closed is not a polygon
