Trigonometry Two Unknown Values
I have a problem with this question, Can any tell me if i did anything wrong in this question? and give me clues on how to proceed from where i left off
y=d*(tan(32)) Equation 1
y=d*(tan(69)) - 7.8 Equation 2
Sub equation 1 into equation 2
d*tan(32) = d*(tan(69)) - 7.8
That's where i'm stuck at the moment, i don't really know if my working out is correct, can anyone help me?
I'm trying to find "d" by the way
