God bless you!!
God bless you!!
We can't help you without the pictures. And only a few of us tutors can post links.
Oh, guys, the answer was 3 cm by the way
Assuming you wrote down the vertices in the standard corresponding pattern, that is
A --> D
B --> E
C --> F , then
notice that 4.5/3 = 7.5/5 = 3/2
x/2 = 3/2
x = (3/2)(2) = 3
A --> D
B --> E
C --> F , then
notice that 4.5/3 = 7.5/5 = 3/2
x/2 = 3/2
x = (3/2)(2) = 3
