Please solve no explanation needed

Option 3

Step-by-step explanation:

I know you said no explanation is needed but I'm going to give it anyways

(1)     Semester 1 and 2 have the same interquartile range (12) so it can't be option 1.

(2)    Semester 1 and 2 have the same median so it can't be option 2.

(3)    Option 3 is true, semester 2 does have the greater mean.

(4)    Semester 1 have the greater third quartile so option 4 can't be true.

Step-by-step explanation:

2x+35+3x+15=90(being perpendicular)

5x+50=90

5x=90-50

x=30/5

x=6

Angle N=2x+35

=2*6+35

=12+35

=47 degree
