Find the value of x
in the isosceles triangle shown

Given that the isosceles triangle has sides √45, √45 and x.

The triangle has a height of 3 units.

We need to determine the value of x.

Value of x:

The value of x can be determined using the formula,

Where b is the base of the triangle, a is the sides of the isosceles triangle and h is the height of the triangle.

Substituting , and in the above formula, we get;

Squaring the terms, we have;

Subtracting, we get;

Thus, the value of x is 12

Hence, Option B is the correct answer.
