with respect to the 45 degree angle, we can add these labels |dw:1441154698897:dw|

which trig function will we use?

  • anonymous
tangent
jim_thompson5910
  • jim_thompson5910
yes since tan(angle) = opp/adj
jim_thompson5910
  • jim_thompson5910
so tan(45) = h/100
jim_thompson5910
  • jim_thompson5910
are you able to isolate h in `tan(45) = h/100` ?

no clue
jim_thompson5910
  • jim_thompson5910
it might help to evaluate tan(45) first use this calculator http://web2.0calc.com/ to find the value of `tan(45)` and tell me what that is

yep
jim_thompson5910
  • jim_thompson5910
so `tan(45) = h/100` is the same as `1 = h/100`
jim_thompson5910
  • jim_thompson5910
so h = ??

100

good

this is a 45-45-90 triangle with congruent legs

wait is that it? 100 is the answer?
anonymous
  • anonymous
thanks :D
jim_thompson5910
  • jim_thompson5910
yeah you multiply both sides of `1 = h/100` by 100 to isolate h, you'll find that h = 100
