The bases of an isosceles trapezoid are 12 and 42 the side is 39 find the bottom of the trapezoid diagonal.

| The diagonal of an isosceles trapezoid is found by the formula:
d = √ (ab + c ^ 2),
where a is the length of the larger base (a = 42 conventional units), b is the length of the smaller base (b = 12 conventional units), c is the length of the lateral side (c = 39 conventional units).
The diagonal of an isosceles trapezoid given by condition is equal to:
d = √ (42 * 12 + 39 ^ 2) = √ (504 + 1521) = √2025 = 45 conventional units.
Answer: d = 45 conventional units.
