What triangle is a 30-60-90 triangle ?

When talking about 30-60-90 triangles it is most helpful to look at their angles. One will be a 90 degree or right angle, theother will be a 60 degree and the final one will be the 30 degree.

Step-by-step explanation:

To find their lengths.

They hypotenuse if 2 the length of the shortest length, if you are given the shortest side simply multiply by two to get the hypotenuse. If you are given the hypotenuse divide it by two to get the shortest side. To get the middle side multiply the short side by most equations wont ask you to simplify that.

i think the answer is b

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
