Find the length of x exactly. Brainly!!

NNADVOKAT [17]

Answer:

x = 7

Step-by-step explanation:

We can tell by looking at this triangle that this is a <u>45 45 90 triangle.</u>

In this situation, the hypotenuse is $x\sqrt{2}$ and the legs are both $x$ .So if we look at the hypotenuse, we can tell that x, or the leg of the triangle, is 7.

45 45 90 triangles: This is a special triangle in which the angles of the triangle are 45 45 and 90 degrees. This means that the hypotenuse will be $x\sqrt{2}$ and the legs of the triangle will be $x$ . You can usually use the Pythagorean theorem to solve the missing sides.
