Pls help me with this lol

a) 42

b) 23

F) 115

Step-by-step explanation:

First, find the angles that are missing in triangle CD1F. (D1 being the inside angle of the triangle)

D1 make a line with 157 and results in 180.

Therefore, 180 - 157 = 23

Now you can find F, 180 - 42 - 23 = 115

A and C are vertical opposites and have the same angle, so 42.

B = 180 - 115 - 42 = 23

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.
