With ASA, we need two angles and an included side. An included side is one that is between the two angles.
But, we need to make sure the sides match up. So, triangle KJI is congruent to triangle ZYX.
Therefore, we need to know that side JI is congruent to YX.
Hope this helps!
Answer:
11
Step-by-step explanation:
378 / 18 = 21 // Money p/h
231 / 21 = 11
No, 3+13>14. If it were a right triangle both sides would be equal
I'm sure you know the formula for Pythagoras Theorem.
The formula is 
C = Your hypotenuse
A + B = The other two adjacent sides.
So you plug in the numbers

And you'll get the answer, which is 56.
