A light pole is supported by two wires that extend from near the top of the pole and are anchored to stakes on either side of the pole. The wires meet at an angle of 80°. One of the wires forms an angle of 62° with the ground and has a length of 13 meters. To the nearest meter, approximately how far apart are the two stakes that anchor the two wires to the ground?

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.

The principal, real, root of: 50−−√2=7.071067817.07106781−7.0710678150 is not a perfect square
