Question

A right triangle is shown below.

What is the value of x rounded to the nearest ten, if necessary?

Answer 1

hmmmmm.... i'm only in 7th grade and to be honest i don't really know but i'll try on this. am i going to be doing this this year?

So from my logic in my empty brain: 4.2?

Explanation:

Because i flipped the pic around and so ,

First i got "x" in my brain and turned it into 9 from 8.5

then 9 divided by 8.5

wait a sec i just realized i made the most dumb mistake by dividing welp i'll just put out what i just fixed in my head and yea here ya go.

B+ for effort ?

Z- for iq?! .-.?

Answer 2

8.5^2=4^2 + x^2

72.25=16 + x^2

56.25 = x^2

x= 7.5
