Question 15284
Let x = smaller angle
5x = larger angle

x + 5x = 120
6x = 120
x= 20 degrees -- smaller angle
5x = 100 degrees -- larger angle


Now consider the choices.  
1.  They are NOT supplementary since they do not add up to 180 degrees.
2.  They are NOT complementary since they do not add up to 90 degrees.
3.  They are NOT both acute since the larger angle is larger than 90 degrees.
4.  One angle is acute and the other is obtuse.  This is true.
