Check the picture below.
now, we know that the slanted legs are congruent, since it's an isosceles trapezoid, we also know that the bases are the parallel sides, so, the "altitude" or distance from those bases are the same length, for each of those triangles in the picture.
now, the bases are parallel, that means the altitude segment is perpendicular to the base, the longest side at the bottom, so, we end up with a right-triangle that has a Hypotenuse and a Leg, equal to the other triangle's.
thus, by the HL theorem for right triangles, both of those triangles are congruent, and if the triangles are congruent, all their sides are also, including the ones on the base.
Answer:
x + 10
Step-by-step explanation:
We know we sold 200 child tickets. There are 37(23) total seats, so that leaves
37(23) - 200 = 651
adult tickets sold and a total door of
8(651)+6(200) = 6408.
The manager's estimate of 6400 is very close.
