Answer: second option.

Explanation:

Find the distance AE by subtracting AB and DC and dividing by 2:


AE=(AB-DC)/(2)\\\\AE=(24-12)/(2)\\\\AE=6

Knowing the length of DE and AE, you can apply the Pythagorean Theorem to calculate the distance AD, which would be the hypotenuse of the triangle ADE:


a=√(b^2+c^2)

Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.

Then:


a=AD\\b=AE=6\\c=DE=8

Substituting values into
a=√(b^2+c^2) you get that the lenght of AD is:


AD=√(6^2+8^2)\\AD=10
