What is the value of a + b?

125

Step-by-step explanation:

A is an inscribed angle. The central angle is 90, so angle A is 45.

110/2 = 55

180 - 45 - 55 = 80

Angle B is 80.

80 + 45 = 125

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.
