Aregular polygon has an interior angle of 170 degrees. (i need with the formulas)

What is the relationship between all triangles that can be drawn given the same three angles

Need match the functions with correct transformation. f(x) = -3x f(x) = |x-1|+3 f(x) = √(x+3) 1/2x² f(x) = (x+1)²-3 4|x| 1. compress by a factor of 1/2 2. stretch by a factor of 4 3. shift to the left 3 4. shift to the left 1 5. shift up 3 6. reflection

What would the rule be for the reflection of y=-3
