Question

What does X equal in this 30-60-90 triangle?

Answer 1

Well in a 30-60-90 triangle there are 2 rules

The short leg is “x” (for now)

The hypotenuse leg is twice the shorter leg (2x)

And the longer leg is x√3

Now using that information we can tell that the hypotnuse here is 19. It’s flipped over.

We know that x is the shorter leg here. So its half of the hypotnuse (19).
19/2 = 9.5

X= 9.5
