Solution:

We know that:

  • The base angles are equivalent.

This means that:

  • This triangle is an isosceles triangle.
  • The legs of the triangle are equivalent.

Let's use Pythagoras theorem to find z.

Finding z using Pythagoras theorem.


  • (8√(x) )^(2) = z^(2) + z^(2)

  • (8√(x) )( 8√(x) ) = 2z^(2)

  • (8)(8)(2)= 2z^(2)

  • (8)(8)= z^(2)

  • 64= z^(2)

  • √(64) = \sqrt{z^(2)}

  • 8 = z

Thus, the value of z is 8.
