Answer:
x = 
Step-by-step explanation:
Based on the Pythagoras theorem, where a and b are the legs of the triangle and c is the hypotenuse.

Therefor x = 
a²b is the same thing as ba²
b and a are two separate variables lets pretend a is 2 and b is 3
2² * 3 = 4 * 3 = 12
3 * 2² = 3 * 4 = 12
this is the commutative property of multiplication
Answer:
AB = CD = 3√5
Step-by-step explanation:
We use Pythagoras' Theorem.
AB² = CD² = 3²+6² = 9+36 = 9·(1+4) = 9·5
=> AB = CD = √(9·5) => AB = CD = 3√5
