Answer:
Step-by-step explanation:
Given triangles are similar, so we setup a proportion
(140-x)/81 = x/9
solving gives x = 14
AC = 140-x = 140-14 = 126
Answer:
No because when you set it up it would be 11/9.4 which equals 1.17
Then you do the other side, 10/8.4 which equals 1.19
And 1.17 doesn't equal 1.19 so they are not similar
Answer:
30
Step-by-step explanation:
A=(a+b)/2xh
A=(6+9)/2x4
A=15/2x4
A=7.5x4
A=30
A. (-3,0) thats the answer i have
