Answer 4

Even though you're saying that you're missing the long side of the triangle, it still will not be longer than the hypotenuse, which is the longest side of the 3.

Answer 5

Here's how it will look, but you don't need a picture to do the math. What would you use? It's a theorem.

Answer 6

theorem 5-12?

Answer 9

if x = 5 then plug into (missing side) = x sqrt(3)

Answer 10

8? im totally confused:((

Answer 11

(missing side) = x sqrt(3)
plug in 5 for x
that would be your answer

Answer 12

so its 8?

Answer 14

no... what do you get when you plug in 5 for x
into x sqrt(3) ?

Answer 15

The triple for the 30-60-90 is this: (x, x sqrt 3, 2x). The x represents the shortest side, which here is 5. That's why the hypotenuse is 10...5*2 is 10. For the other leg, you have\[x \sqrt{3}\]If x is 5, then what is the measure of that leg?

got it thnx:))
