Question 749108
1.) t = 3pi/4 (which I got; 135 degrees counter clockwise, Quadrant II angle) 
2.) t = -2pi (also good; 1 full rotation clockwise, quadrilateral angle)
3.) t = -2 (lost me) 
4.) t = 117 (same issue as the last).
***
3π/4, -2π, -2, and 117 are in radians which are real numbers as you said.
To illustrate:
1.) t = 3pi/4 =2.3532..radians=135º
2.) t = -2pi=-6.28 radians=0
3.) t = -2=-2 radians=-2/π*180≈-114.59º
4.) t = 117=117 radians=117/π*180≈6703.61º
note:special angles like 30º, 60º, 45º, etc are written in terms of π for ease of calculation and explanation but angles in-between are expressed as real numbers without π.
Hope this helps.
