Answer:
KL= 17.67 unit
UE = 17.67 unit
Step-by-step explanation:
Given:
Diagonals 
KL= h+7 
UE = 4h-25
Find:
Length of diagonals KL and UE
Computation:
We know that in isosceles trapezoid the length of diagonals are equal
So,
KL = UE
h+7 = 4h-25
3h = 32
h = 10.67
So,
KL= h+7 
KL= 10.67+7 
KL= 17.67 unit
UE = 4h-25
UE = 4(10.67)-25
UE = 17.67 unit

Ladder makes a right triangle with the wall and ground. The hypotenuse = length of the ladder = 10 ft 
Let the height be h
By Pythagorean theorem 
10^2 = 3^2 + h^2 
h^2 = 10^2 - 3^2 = 100 - 9 = 91
h = sqrt( 91) = 9.54 ft
