The measure of one of the smaller base angles of an isosceles trapezoid is 60 degrees. The shorter base is 5 inches long and the altitude is sqrt(3) inches long. What is the number of inches in the perimeter of the trapezoid?
+2668 Note that we have a 30−60−90 triangle with the longer leg being √3. This means that the other leg is 1, and the hypotenuse is 2.
This means that the length of the longer base is 5+(2×1)=7.
So, the total perimeter is 7+5+(2×2)=16
