Use the formula (n-2)*180 where n is the number of sides on the polygon.

If two lines are parallel, then they will have the same gradient. The gradient of the curve is represented by m in the equation y=mx + c. For this question, if L2 is parallel to L1, m will therefore equal...

4(3x-2)=2x-5
Expand the brackets: 4(3x)-4(2)=2x-5 ---> 12x-8=2x-5Collect like terms, but beware of sign changes: 12x-2x-8=-5 (subtract 2 from both sides of the equation) -----> 10x...
