Answer:
x = √40 = 2√10

Explanation:
The given triangle is an isosceles triangle. This means that the angle bisector is perpendicular to the base and bisects it, which means that we now have two identical right-angled triangles.

Let's consider the triangle on the right:
We have one of its sides = 6 units, the other one = 4/2 = 2 units and the hypotenuse = x units

We will use the Pythagorean theorem to get the length of the hypotenuse as follows:
(Hypotenuse)² = (side1)² + (side2)²
x² = (6)² + (2)²
x² = 36 + 4
x² = 40
either x = -√40 = -2√10 ........> rejected as length cannot be negative
or x = +√40 = 2√10 .........> accepted value

Based on the above:
x = 2√10 units

Hope this helps :)

What is the median in math
djyliett [7]
In math, the median in a group of values is the value that is closest to the center of the group when the values are organized from least to greatest.

For example, in the group [50, 51, 53, 56, 67], 53 would be the median, because it is in the middle of the group.
Hope that helped =)
