PLEASE HELP! What is the value of x to the nearest degree? (image below)
here two sides are given..and with reference angle x can you guess some trigonometric relation??
x = 19 degrees?
thats not the answer..I have given you the definition of sinx previously..do you know such formulas for tanx,cosx..
no....im really terrible at this
with reference to what i have told you previously..cosx=base/hypotenuse.. tanx=perpendicular/base..
which sides are given in this fig..p,b or h??can you say..
p and b?
yes
so which formula do you have to use cosx or tanx??
tanx?
yes,so what will be the value of tanx??
what is the tanx formula?
i have given you above:)
3?
its p/b..can you identify p and b in above fig..Try again to find tanx..i have already explained about p,b,h
x/11?
here p=11 b=33 so tanx=11/33=1/3 \[x=\tan^{-1} (1/3)\] if you calculate \[\tan^{-1} (1/3)\] in calculator you'll get around 18.43 which is the ans
