Answer:
Question 9: A. 27/2
Question 10: A. 9/2
Step-by-step explanation:
I believe Silem2020 is correct, I Checked on paper.
Q#9: A 27/2
Q#10: A 9/2
<u>Q#9:</u>
these triangles are similar so we have to take the ratios:
8/(12+8)=8/20
8/20=9/(9+x)
8*(9+x)=20*9
72 +8x=180
108=8x
x=27/2
<u>Q#10:</u>
6/10=x/(12-x)
6(12-x)=10x
72-6x=10x
72=16x
x=9/2
5, x = 0, y = -2
6, x = 4, Y = 9
7, X = -2, Y = -2
