Answer:
The height of the right trapezoid is
Step-by-step explanation:
Let
x ----> the height of the right trapezoid in units
we know that
The perimeter of the figure is equal to
we have
---> because is a square
substitute
-----> equation A
<em>In the right triangle CDH</em>
so
Remember that
so
substitute the values in the equation A
-----> equation A
y = - 25
since x varies directly with y then we can express the relationship as
x = ky ← k is the constant of variation
to find k use the given condition y = - 10 when x = 4
k = =
= -
hence x = - y
when x = 10
10 = - y
multiply both sides by - 5 and divide both sides by 2 )
- 50 = 2y ⇒ y = - 25
