The trapezoid in the figure has equal nonparallel sides. the upper base is 6, the lower base is 16, and the diagonal is 12. what is the altitude of the trapezoid? a. 7.9 b. 4.8 c. 5.7 d. 8.4

To find this I would use the pythagorean theorem which is:

a^2 + b^2 = c^2

Since we already know c = hypotenuse, and a side of the shorter sides we can plug them it like this:

11^2 + b^2 = 12^2

121 + b^2 = 144

b^2 = 23

√23 = 4.79

Round:

B. 4.8 would be your answer!
