Hello
I was hoping some one could check if i have understood this correctly.
I have an angle of sin(theta) = 10/45
From this i can calculate that the adjacent must be of length 5sqrt(77). So to find the secant i can do:
sec(theta) = 1 / (5sqrt(77)/45)
Thus sec(theta) = 45/5sqrt(77)
My question though is, if i am given the angle sine(theta) = 10/45 should i just be assuming it is a right angled triangle like i did in order to find the length of the adjacent? Have i understood this correctly? I keep doubting myself as having understood it correctly.
