Answer:
Since y° +28° is a right angle,
y= 90° -28°
y= 62°
x= 180° -62° (adj. ∠s on a str. line)
x= 118°
The sum of the angles on a straight line is 180°
The point (2, -5) would not be one of the correct vertices of the reflected shape.
When we reflected a shape across the line y=x, we just replace the x's with y's and y's with x's.
Our new points are (5, 2) (4, 6) and (3, 3). None of the points contain negative numbers.
f(3) means value of y when x = 3
So, the answer is 2
