Question

The value of x is 12.

Answer 1

false i think because if it's 12 the angle of triangle should be 60°

Answer 2

Answer: False

Step-by-step explanation:

45-45-90 is a special triangle because there is a specific relationship between the legs and the hypotenuse: a - a - a√2

So, If the leg of the 45-45-90 triangle is 12, then the hypotenuse (labeled as x in your drawing) will be 12√2.
