The coordintates of the point mark the opposite-leg and adjacent leg of a right triangle.
The opposed-leg is the y-coordinate, this is 3.
The adjacent-leg is the x-coordinate, this is 4.
The tangent of the angle q is given by:
tan(q) = y-coordinate / x-coordinate = 3 / 4 = 0.75
Answer: 0.75
Answer:
"unchanged"
Step-by-step explanation:
Congruence transformations (translation, rotation, reflection) do not change lengths, angles, area (of 2D figures), or volume (of 3D figures). The area would remain unchanged.

Answer:
all work is pictured and shown
Answer is choice C
"Dilate with a scale factor of two" means "multiply each coordinate by two"
A = (2,3) turns into A' = (4,6)
B = (3,5) turns into B' = (6,10)
C = (7,4) turns into C' = (14,8)
Side Note: this quick shortcut only works if the center of dilation is the origin (0,0). If the center of dilation isn't the origin, then you will have to do a translation (shifting) before you can use the trick, and then you'll have to shift back. The idea of the shifting is so that the center of dilation becomes the origin on a temporary basis. Because no mention is made of the reference center, it is assumed to be the origin by default.
