Answer:
Option A. is the correct option.
Step-by-step explanation:
By the theorem of similar triangles, when two triangles are similar their corresponding sides will be in the same ratio.
In ΔABC and ΔDEF
So, these two triangles will be similar.
Option A. ΔABC and ΔDEF are similar because
25.12 millimeters is your answer.
Circumference can be solved by using the equation:
c = 2πr or c = πd
Note that diameter (d) is equal to 8. Plug in 8 for d.
c = (8)(π)
Also note that π = 3.14. Multiply
c = (8)(3.14)
c = 25.12 millimeters.

1,4(0,5x + 4,2y) - 3,5(0,2x - 1,5y)
1,4.0,5x + 1,4.4,2y - 3,5.0,2x + 3,5.1,5y
0,7x + 5,88y - 0,7x + 5,25y
0,7x - 0,7x + 5,88y + 5,25y
11,13y
31°
missing angle= 90-59= 31°
(90 because there is a square which represents 90 degrees)
hope it helps ☺️
