The diagonal of a tv is 28 inches long. assuming that this diagonal forms a pair of 30-60-90 right triangles, what are the exact length and width of the tv?

30-60-90

shortest leg is always x ; longest leg is always x√3 ; hypotenuse is always 2x

hypotenuse = 28 inches = 2x = 2(14)
shortest leg = x = 14
longest leg = x√3 = 14√3

The exact length and width of the tv would be 14 inches and 14√3 inches.

Ithink the answer is c

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
