Answer:
Question 1:
8/12 = 4/6 = 3/x
0.6 = 0.6 = 3/x
It is a similar triangle, therefore 3/x = 0.6
x = 5 because 3/5 = 0.6
Question 2
You did that correct :)
Question 3:
"Check all that apply"
B
D
Question 4
You got question 4 wrong since similar triangles have similar ratio.
8/10 = 8/10 = 10/14
0.8 = 0.8 = 0.7
Correct answer for question 4 is B("No they are not similar because the ratios are not equal")
Question 5
The Quadrilaterals are similar. Therefore:
22.4/14 = 12.8/8 = 12/7.5 = 26/x
1.6 = 1.6 = 1.6 = 26/x
Meaning 26/x = 1.6
x = 16.25
Because 26/16.25 = 1.6
Hope that helps :)
