It is soo easy friend

 

[tornado]

you have to make a new triangle
from A and to the right
then go down to T

 

[Hamzeh S]

simple extend north of T and draw a line to the right from north of A it should give u a right angled triangle and use cosine sin and tan rules for right angled triangles

Thats what I did guys, but the thing is you don't have any of the angles in the triangle except the right angle, will that be okay to use? And if you can, please solve it here so that I can understand how to do it

Ohhh
Never mind guys I got it, you use the angle which is 55 degress and then sin etc..

Thanks anyways
