It depends on which letter you are looking at, but in for this triangle the hypotenuse will always be AB. The adjacent side is the one “left” or “right” of the latter you’re looking at, but never the hypotenuse (stays the hypotenuse). So if you’re looking at “B”, the adjacent side is CB or 21, while AC or 20 is the opposite

Answer:
Step-by-step explanation:
Hello, please consider the following.
We have two equations:
(1) -2x - 4y = 20
(2) -3x + 5y = -25
5*(1)+4*(2) gives
-10x - 20y -12x + 20y = 100 - 100 = 0
-22x = 0
x = 0
I replace in (1)
-4y = 20
y = -20/4 = -5
There is one solution x = 0, y = -5
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
