C- 5 less than 6 times some number.
5 - 6t
Draw the shape by drawing dots at the co-ordinates.
Connect them in order, so if it's KLMN, connect K to L then to M then N.
Then, pick one of the points, I'd choose K, then move that dot 3 to the right, then move it 4 up. Do the same for all of the letters.
The measure of angle 6 is 84 :)
If 5 is 5%, then we can say that 1 is 1%, so we can multiply by 100 to get 100% which is 100, your answer. I hope this helps!
If you let me know what you are trying to find and measure I will help you with the answer in the comments. Sorry not enough info from this.
