The hypotenuse of a right triangle measures 10 inches and one angle is $45^{\circ}$. What is the number of square inches in the area of the triangle?
Sin(45)=Opposite side/Hypo
.707107...=OS/10
OS=.707107 x 10=7.07107
Since it's equilateral triangle, then the Adjacent side is the same as above=7.07107
Area=1/2(7.07107) x 10=35.35535....
