Answer:6. 6x2 =12
Step-by-step explanation:
Answer:
x = 20
y = 20√2
Step-by-step explanation:
This is a 45 - 45 - 90° special right triangle
In a 45 - 45 - 90° triangle the legs are congruent and the hypotenuse = leg * √2
If one leg = 20 then the other leg also = 20
Thus, x = 20
If leg = 20
Then hypotenuse = 20 * √2 or 20√2
Thus, y = 20√2
