the trapezoid has equal nonparallel sides the upper base is 6. the lower base is 16. and the diagonal is 12. what is the attitude of the trapezoid?
draw the figure. Draw the diagonol. Notice that 5 is the overlap on each end of the base from the upper base downward. Now look at the right triangle 12-11-h (the 11 is 16-5).
12^2=11^2+h^2 solve for h.
