Answer:

x = 36 , 2x = 72 , 3x = 108 , 4x = 144

Step-by-step explanation:

2x = P+Q      (ΔABC, exterior angle property)

4x = R+S       (ΔDBC, exterior angle property)

4x + 2x = P+Q+R+S = (P+R) + (Q+S) = (180 - 3x) + (180 -x)  (supplementary)

6x = 360 - 4x

10x = 360

x = 36

2x = 72

3x = 108

4x = 144

check: sum of interior angles = (180 x 4) - (36+72+108+144) = 360

What set of transformations is performed on triangle ABC to form triangle A'B'C'?
jonny [76]
In order to answer this question, you would need to provide a coordinate, but since this question lacks that, I will explain transformations. Transformations are like moving an object throughout a room, in this case, the room is a graph. The Y coordinate
(X, Y) is moving things higher or lower, or in this case up and down the graph. The X coordinate (X, Y) is moving things forward and backwards, or left and right on the graph. So in order to find your Transformation, you need to take what was your item's original position, it's X and Y locations, and subtract from that your new location.

Here's an example, if I had a triangle with sides and corners labeled A, B, and C or for short, triangle ABC, if A is located at (1 , 0), B is located at (3 , 3) , and C is located at ( 5 , 0) what is its new transformation if it is moved up 3 and right 1?

You would then add 1 to each angle's X coordinate and add 3 to each angle's Y coordinate. Resulting in this:
A (2 , 3)

B (4 , 6)

C (6 , 3)
