Answer:
The answer is 29.
Step-by-step explanation:
a straight line is 180 degrees, to subtract 77 from 180 to figure out the red angle. Which is 103 degrees as shown also in red. Now we add 103 and 48 which is 151 degrees. And since all straight lines are 180 degrees, that means that angle p has to be 29. If you add 29 to 151, then you get 180 degrees.

Answer:
A" (-3, 0)
B" (9, 9)
C" (9, 0)
Step-by-step explanation:
The hint explains how to get the final coordinates.
The original figure ABC has vertices
A (-3, -1)
B (1, 2)
C (1, -1)
There are two separate transformations for this triangle, so let's take it one step at a time
The first transformation is a translation by the vector <2, 1>, This means we get a new figure A'B'C' where we add 2 to each of the x coordinates of the original figure and 1 to the y coordinates of the original figure
For A which is (-3,-1) the transformed coordinate becomes:
A -> A' -> A' (-3 + 2, -1 + 1) => A'(-1, 0)
Similarly
B(1, 2) -> B' is B'(1 + 2, 2 + 1) => B'(3, 3)
C(1, -1) -> C'(1 + 2, -1 + 1) or C'(3, 0)
So the first transformation results in a triangle A'B'C' with the following coordinates:
A'(-1, 0)
B'(3, 3)
C'(3, 0)
The second transformation is a dilation of A'B'C' which results in an expansion or compression of the image depending on the scale factor. Here the scale factor is 3 so the image is expanded by a factor of 3
Dilation simply requires you to multiply both x and y coordinates oof A'B'C' by 3
A' (-2 , 0) -> A"(-1 x 3, 0 x 3) => A"(-3, 0)
B'(3, 3) -> B"(9, 9)
C'(3, 0) -> C"(9, 0)
I have attached two images showing each of the transformations separately to give you a better idea
