Find the value of x and the value of y

This is a 30-60-90 triangle. In a 30-60-90 triangle, the longer leg is √3 times longer than the shorter leg, and the hypotenuse is twice the length of the shorter leg.

Longer leg: shorter leg * √3

Hypotenuse: shorter leg * 2

In the diagram, the shorter leg would be 18/2 = 9. x is the longer leg, so x would be 9√3. y is the hypotenuse, so y would be 9*2 = 18.

x (longer leg) = 9 * √3

y (hypotenuse) = 9 * 2 = 18

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
