Question

What is the value of x?

Answer 1

The value of x is more 90 because the angle is an obtuse and an obtuse is more than 90 degrees. 

Answer 2

Use the Pythagorean theorem (a^2+b^2=c^2) because it is a perfect triangle. Since both sides are equal take the square root of 50. So X is about 7.07106781.
