In my opinion these are some of the hardest questions that the sat tests you on. The triangle could be larger smaller or turned around but that angle will always have that ratio.

Now i don t blame them. In a right triangle the side that is opposite of the 90 angle is the longest side of the triangle and is called the hypotenuse. Recently i ve been tutoring for the sat and i noticed one of my students was struggling with some of the sat math questions. So angle w plus 155 degrees is equal to 180 degrees.
