If a football player positioned on the scrimmage line runs straight downfield for 26 yards

In the problem you are given what basically amounts to two sides (the legs) of a right triangle.

 We are trying to find the hypotenuse of the triangle (which is the displacement).

 Using the Pythagorean Theorem 

 a^2+b^2=c^2 

 we will plug in 26 and 6 for a and b, and then solve for c yielding an answer of 26.6833 yards.

 To find the angle from the direction he ran forward, we can use a trigonometric function.

 I will use the tangent function since we are given the adjacent and opposite sides (tanθ=(opp/.adj.) 

 tanθ=(6/26).

 This yields a theta value of 12.9946 degrees (this is the angle from his initial running direction)

hope this helps :)

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
