hello brainly team I need help

Answer:
98 feet
Step-by-step explanation:
x=22 (I know this isn't an option however, I've reviewed this problem multiple times, but only find x=22 to be correct. You can look at my explanation below to see what I see.
[tex]according\ to\ the\ title\\ the\ diagonals\ of\ an\ isosceles\\ trapezoid\ are\ represented\\ b_y(6x-29)\ and\ (4x+15)\\ so\ 6x-29=4x+15\\ so\ 2x=44\\ so\ x=22[/tex]
Answer: B) 98 feet
[tex]solution:\ From\ question\\ 84\ feet\ long\ and\ 50\ feet\ wide\\ so\ he\ will\ run\ \sqrt{{84}^2+{50}^2}\approx98\ feet[/tex]
I hope this helps you
