This is a demo of SAT Math Section 2. Your next practice questions in a specific program will be specially tailored for you as the system learns from your previous practices!

What is the sum of degrees of ∠X and ∠Y, i.e. X + Y = ? Note that the diagram might not be drawn to scale and all the units are in degrees(°).
