Find the value of x in the isosceles triangle shown below.

Answers

Answer:

x=8

Step-by-step explanation:

This isosceles triangle is composed of two right triangles with sides 8,√(80) , and y

As we have two sides of a right triangle, we can find the third using the Pythagorean Theorem

(√(80) )^2=8^2+y^2\n\n80=64+y^2\n\ny^2=16\n\ny=4

As this is an isosceles triangle, these two right triangles are equal, this means that x=2y

Therefore, x=2(4)=8

Answer:

x=8
