Step-by-step explanation:
cosine is cos(angle)= adjacent/hypotenuse
sine is sin(angle) = opposite/hypotenuse
Tangent is tan(angle)= opposite/adjacent
for all of those
if the equation is something like tan(69)= x/69
multiply both sides by 69 so it will end up as x=69tan(69) and put that in the calculator
if it is something like tan(69)= 69/x
just swap x and tan(69)
it is much easier
it will then be 69/tan(69) and put that in the calculator
