To find the horizontal and vertical components of a vector, construct a right triangle with one angle of 11.7 degrees, and a hypotenuse of length 26.3.

To find the vertical component, recognize that the sin 11.7 = y/26.3

solve for y = 5.333 m

To find the horizontal component, recognize  that the cos 11.7 = x/26.3

solve for x = 25.754 m
