A fence post is 6 m tall and casts a shadow of 8 m. Find the angle of elevation.
Remember the tangent function relates opposite and adjacent sides.
In a triangle with a right angle, if one side is 9 cm and the other is 12 cm, what is the hypotenuse?
Don't forget to square each side!
In a right triangle, if one side is 12 and the other is 16, what is the length of the hypotenuse?
