theta=(T) pie=(P) beta=(B)

1) simplify: (3(P)/2+(T))

2)if tan x = 2 find tan((P)/4+x)

3)if tan(T)= -12/5 and (T) lies in quadrant 2, then what is the value of cos2(T)

4)if cos(B)= -1/3 and (B)is a second quadrant angle find the tan2(B)

5)if sin A= -3/5 in quadrant 3, find cos2A

HERE ARE THE ANSWERS I JUST NEED THE WORK:

1)-cos(T)

2)-3

3)-110/169

4)4root2/7

5)7/25
