Work out the sizes of the ANGLES

Step-by-step explanation:

In quadrilateral ADEF

r + 95 +100 +110 = 360  {Sum of all angle of quadrilateral}

               r + 305 = 360

                        r = 360 -305

r = 55

In triangle AEC,

r + 95 + t = 180

55 + 95 + t = 180

    150 + t = 180

             t = 180 -150

t = 30

In triangle ABD,

r +s + 100 = 180

55 + s + 100 = 180

      s + 155 = 180

            s = 180 - 155

s = 25

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
