Question

The length of the hypotenuse of a 30-60-90 triangle is 10. find the perimeter.

Answer 1

Sides of a 30-60-90 triangle look like this:

Answer 2

You know the hypotenuse is 10, so you have:



You need to find the other two sides (by finding x) and then add all three sides for perimeter.

Answer 3

Ok so does that mean for x^2(3) I would do 10^2(3)? which would be 300?

Answer 4

There is no x^2(3). It's \[\large x \sqrt3\] on the left.

Answer 5

And 2x = 10 so from that you can find x.

Answer 6

x=5 right

Answer 7

Yes, now you can find the other two sides.

Answer 8

okay thank you
