Only figure C is a regular polygon since it has all sides congruent and all angles congruent.
Answer:
C) -3x=-3
Step-by-step explanation:
When you subtract the 3x-y=7 from 6x-y=10, you will receive the following equation:
3x-6x-y-(-y)=7-10
-3x-y+y=-3
-3x=-3
As we can see, this equation matches the one in option C, meaning that it's our answer!
It would lie between 180 and 220
They are used for making the sides of a triangle into a ratio. Sine is opposite of the angle divide by the hypotenuse, cosine is adjacent divided by the hypotenuse, and tangent is the opposite divided by the adjacent. Sine is the y-component, cosine is the x-component, and tangent is the ratio of sine/cosine or can also be considered the slope.
