Given tanx=8/15 when pi &lt; x &lt; 3pi/2, find tan x/2.
S_A_V [24]

Answer:

tan(x/2)=-4

Step-by-step explanation:

we know that

The angle x belong to the III quadrant -----> given problem

step 1

Find the angle x

x=arctan(8/15)=28.07\°

Remember that the angle x belong to the III Quadrant

so

x=28.07\°+180\°=208.07\°

step 2

Find angle x/2

x/2=208.07\°/2=104.035\°

step 3

Find tan(x/2)

tan(104.035\°)=-4
