Answer:
x = 5
Step-by-step explanation:
the supplementary angle of (19x-18) = 180 - (19x-18) = 198-19x
all interior angles of a triangle = 180 degrees
180 = (7x+1) + (10x-9) + (198-19x)
180 = 7x+10X-19x+1-9+198
180 = -2x+190
-2x = -10
x = 5
The correct answer among the choices provided is the third option. The length of the line C'D' is 6.75 units but it does not pass through A. The first step is to multiply 4.5 with the scale factor which is 1.5. 6.75 is the product and the answer of the problem.
