Answer:
x = √41
Explanation:
Given a right trapezoid with bases 10 and 14, and height 5, you want the length of the angled side, x.
Pythagorean theorem
The length x is the hypotenuse of a right triangle with one leg 5 units and the other leg (14 -10) = 4 units. It can be found using the Pythagorean relation:
c² = a² +b²
x² = 5² +4² = 25 +16 = 41
x = √41 . . . . . take the square root
