To solve the value of x in the above equation, here are the steps.
1. Subtract 13 on both sides of the equation.
2. Divide both sides of the equation by 4.
3. Get the square root on both sides of the equation.

-A rhombus is a four-sided figure and all sides have equal length. Opposite sides are parallel and opposite angles are equal.
-A square has equal sides and every angle is a right angle. Opposite sides are parallel.
-A parallelogram<span> has opposite sides parallel and the sides lengths are the same. Opposite angles are equal </span>
Answer:
y = √55
Step-by-step explanation:
All the triangles are similar, so the ratio of short side to hypotenuse is the same for all:
5/y = y/(5+6)
y^2 = 55
y = √55
_____
<em>Comment on the geometry</em>
There are three "geometric mean" relationships that apply to this geometry.
- the altitude BD is the geometric mean of BC and BA (√30)
- the long side of the large triangle is the geometric mean of the longer segment of the hypotenuse and the whole hypotenuse (x = √66)
- the short side of the large triangle is the geometric mean of the shorter segment of the hypotenuse and the whole hypotenuse (y = √55)
If you were aware of the last of these relationships, you could write down the answer without any "work."
y = √(5(5 +6)) = √55
__
The geometric mean is the n-th root of the product of n numbers. When there are 2 numbers, it is the square root of their product.
