You can consider the triangle (as on in the picture) and apply to it composition of two transformations:
1. reflection about the line y=x to form ΔA'B'C' and translation 1 unit right and 5 units up to form ΔA''B''C'';
2. translation 1 unit right and 5 units up to form ΔA'B'C' and reflection about the line y=x to form ΔA''B''C''.
You can see that results are different.
On added picture blue colour responds to composition of transformations 1 and red colour to composition of transformations 2.
Answer:
C
Step-by-step explanation:
Answer:
I think the answer is Option D, 135 degrees.
Since the angles of all of the octagon combined is 1080, divide that by 8 to get 135 which means that all 8 angles are 135 degrees.
IF EC = 8, than we know for sure that the length of AC would be 2 x 8 = 16
The formula to use in determining Rhombus area is
A = (AC . DB)/2 , so the value x could be found with this equation :
72 = 16 (x-1) / 2
72 = (16x -16) /2
72 = 8x - 8
80 = 8x
x = 10
