If you know the law of sines and cosines, you will realize that not every triangle is a right triangle. If all of the three angles add up to 180, then you would say that it is a right triangle. Here is a sheet that you can use if you know sines and cosines law.

They are both not right angles. You can easily tell because you can't draw a square in the corner.

X = y 2 - 1
pochemuha
Your answer would be option B. 2y² - y - 6 = 0. This is because if you were to substitute x = y² - 1 into the equation 2x - y = 4, you would get 2(y² - 1) - y = 4, which expands into 2y² - 2 - y = 4, and then simplifies to 2y² - y - 6 = 0.
I hope this helps!
