Step-by-step explanation: n Euclidean geometry, an isosceles trapezoid is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid. Alternatively, it can be defined as a trapezoid in which both legs and both base angles are of the same measure.
Area: ½ x (sum of the lengths of the parallel sides) × height of the trapezoid
Perimeter: the sum of the top and bottom sides+2(leg of the trapezoid)
To solve for x we proceed as follows: from the laws of logarithm, given that: log_a b=c then a^c=b applying the rationale to our question we shall have: log_5 x=4 hence 5^4=x x=625 Answer: x=625
