Ms harrison tells you that a right triangle has a hypotenuse of 13 km and a leg of 12 km. she asks you to find the other leg of the triangle. what is the length of the other leg to the nearest km?

12^2 + x^2 = 13^2

144 + x^2 = 169

x^2 = 25

x=5

The other leg is 5 km 

The surface area would be 576 because you multiply all the numbers then multiply that number by 6

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.
