These are special triangles. The triangle with a hypotenuse of 11 is a 30-60-90 triangle, and the other triangle in the diagram is a 45-45-90 triangle. For such triangles, the following properties apply.

For 30-60-90 triangles:

If the short leg is x -

· the hypotenuse is 2x

· the long leg is x√(3)

For 45-45-90 triangles:

Their legs are congruent. If their legs are x -

· the hypotenuse is x√(2)

We can find x by determining the length of the legs of the 45-45-90 triangle and using the above property. Notice that one of the legs of the 45-45-90 triangle is also the long leg of the 30-60-90 triangle. By finding the length of the long leg of the 30-60-90 we can determine the length of the hypotenuse of the 45-45-90 triangle.

The hypotenuse measures 11. The long leg is √(3) times the length of the short leg. The short leg is half the hypotenuse, thus the short leg is 5.5. The long leg is 5.5√(3) or . Since this is the length of the legs of the 45-45-90 triangle, the hypotenuse (x) is .

Simplify.

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
