Question

Find y give your answer in simplest form​

Answer 1

`17 √(2)`

One of the angle of the triangle is 90 degrees which means it is a right angled triangle. Two angles are same i.e 45 degrees which means the angle is an isosceles triangle.

so, x = 17 (isosceles triangle)

then use pythagoreas theorem:

`y = \sqrt{x {}^(2) + 17 {}^(2) }`

and x = 17, so simplify and

`y = \sqrt{17 {}^(2) + 17 {}^(2) }`

so

`y = 17 √(2)`
