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?

campbell_st · Answer

well the triangles will be similar, I'd expect. 

so the ratio of sides will be the same

campbell_st · Answer

you would need to post a diagram so people can match sides...

i think x is 8.5 but i dont really know.

as usual can you just give me a problem to solve I am really good at that

rayman5766 · Answer

also it doesn't come with a diagram

@sleepyhead314 pls I beg you medals all day if you help me

rayman5766 · Answer

oh thank god what do I do first teacher

sleepyhead314 · Answer

the ratio of 3 to 5 would be equal to the ratio of 5 to x
so you can get the equation of

$$\frac{ 3 }{ 5 } = \frac{ 5.1 }{ x }$$ do you know about to solve for x from there? :)
