Question

Natalia constructed a right triangle with two side lengths measuring 3 and 5 units. She constructed a second right triangle similar to the first one, with the two corresponding sides measuring 5.1 and x units in length, respectively.

What is the missing length, x, of the second triangle?

Answer 1

Well, you need to set up a scale factor. Do you know how to do that?

Answer 2

no

Answer 3

Okay, well, a scale factor is a way of going from one number to another.
Do you happen to have a picture of these triangles? o.e

Answer 4

no

Answer 5

Okay, well, I'm guessing that the 5 and x correspond while the 3 and 5.1 correspond.
You would need to set up a scale factor (3/5=5.1/x)
Then you cross multiply.
Do you know how to go from here?

Answer 6

no

Answer 7

Multiply 3 and x and then 5 and 5.1 and tell me what you get
