12/30 = 18/45, so first you're going to cross multiply and you'll get (30)(18) = (12)(45). Then you can see that 540 = 540 same number so they're proportional...
BTW THIS WAY IS A LOT EASIER.
12/30 = 2/5
18/45 = 2/5
So yes, in summary, they're proportional to each other. Hope this helps, have a BLESSED and wonderful day! :-)

Hello!
It is given information that this triangle is a right triangle, meaning that the Pythagorean Theorem can apply here.

We can set the length of a leg as an unknown variable
.

Remember that it is the whole
term being squared, meaning that it'll simplify to
, not
.




This means we can plug back in to find the sides.
The hypotenuse would be
, or 4.2.
And the legs would be 1.4 and 4, respectively.
Hope this helps!
