1) 70
2) 110
3) 70
because 110 is equivalent to angle 2. angle 1 and 3 are also equivalent so you add 110 + 110 which equals 220 and subtract 360-220 which equals 140 and divide by 2 to get angles 1 and 3.
We can take out one of the points such as H (2,6) and then take it's dilation H' (1,3)and see that 2 and 6 were both multiplied by 1/2 to get 1 and 3, so the scale factor is 1/2
• Im sorry but we doesnt know the x number :( but dont worry to plot the diagram:
- substitute the number x (given) into the equation f(x)
- example: f(x) = x + 9 / x - 3
- then x given is 4
- therefore, f(x) = (4) + 9 / (4) - 3
- f(x) = 13 / 1 or 13
- then you plot at 13 on the graph :)
hope this helps ;/
