The new triangle is gonna be bigger. But how big? Let’s look at A.
A= 2,8
Look at A’, it’s 6,24. See a pattern??
Multiply 2,8 by 3. It’s triple the amount, therefore the scale factor is 3.
To double check, multiply by 3 to B and C and see what you get.
I can not see the question it is blurry
The answer is 58, because 2/5 is equal to 0.4, and 0.4 multiplied by 145 is 58.
