You can put this solution on YOUR website! In a right triangle the cosine of an acute angle is 1/2 and the hypotenuse measures 7 inches. What is the length of the shortest side of the triangle?
-----
If the cos is 1/2 the side adjacent to that 60 degree angle is (1/2)7 = 3.5 in.
----
That side is opposite a 30 degree angle.
----
Since 30 degrees is the smallest angle the side opposite is
the smallest side = 3.5 in
