tan x =5/12 =o/a
h=sqrt(o^2 +a^2)=sqrt(5^2+12^2)=13
cos x=a/h =12/13
sin x= o/h=5/13

thx :)

astarmathsandphysics:
no probs. so many asking questions atm. I will be here for next few hours at least.

solve the equations for thita. in the interval 0<thita<360 :
sin thita + cos thita=0

astarmathsandphysics:
Take cos theta to the right and divide by cos theta to get tan theta=-1 so theta =-45 the keep adding 180 to get 135 and 315
