Angle 1 = 5x angle 2 = 10x
angle 3 = 15x
angle 4 = 20x
angle 5 = 25x

*given that angles 1 & 2 are complementary AND angles 2 and 4 are supplementary angles

which of the following are correct
1. x = 5 OR x = 6
2. angle 3 is obtuse OR angle 5 is a straight angle
3. angles 4 & 3 are supplementary angles OR angle 4 = 120
