I need this explained I don't understand this

we can write this: \[\tan \left( {45} \right) = 1 = \frac{7}{9} + \frac{2}{9} = \tan \theta + \frac{2}{9}\]

so, we have: \[\tan \theta = \tan \left( {45} \right) - \frac{2}{9}\] then we can state that \theta is less than 45 degrees

so could I sub one of the answers into the equation lets say Tan(38) what could I sub in for that?
Michele_Laino
  • Michele_Laino
yes! try with 38 degrees
BeastBoy17
  • BeastBoy17
so would 2/9 work still o should I use something different

or*

for current exercise, 2/9 works well, since: (2/9)+ (7/9)=1= tan(45)

furthermore, since: \[\tan 30 = \frac{{\sqrt 3 }}{3} > \frac{{1.7}}{3} = \frac{{5.1}}{9}\] our angle \thta has be greater than 30 degrees

ok
BeastBoy17
  • BeastBoy17
its bigger than 30 and less than 45 so which answer would work
BeastBoy17
  • BeastBoy17
so 38 would be the answer??
Michele_Laino
  • Michele_Laino
yes! That's right!
