In the triangle, x = 3. Find y.

A) y = 6
B) y = 7
C) y =
3
D) y = 3
2
E) y = 6
2

Applying the Pythagorean Theorem, it is found that the value is .

The Pythagorean Theorem states that in a right triangle, which has an angle of 90º, the sum of the lengths squared of the sides is equals to the length squared of the hypotenuse.

In this problem:

Hence, applying the Theorem:

Since :

y = 3

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

y² = x² + x² = 3² + 3² = 9 + 9 = 18 ( take the square root of both sides )

y = = = × = 3
