Triangle XYZ is formed by the three squares J, K, and L
So it is a right triangle.
Pythagorean Theorem: a^2 + b^2 = c^2
(XY)^2 + (YZ)^2 = (ZX)^2, because 144 + 256 = 400
The answer is 3
x = 3
The height of the trapezoid with an area of 70.55 sq feet is, 8.3 feet.
A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases.
The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.
The altitude is the measurement of the angle perpendicular to the parallel sides.
We know, The area of a trapezoid is,
(1/2)×(sum of the two parallel sides)×height.
Therefore, From the given information,
(1/2)×(11.4 + 5.6)×h = 70.55.
(1/2)×(17)×h = 70.55.
17h = 141.1.
h = 8.3 feet.
