Question 1184963


{{{sin(A)= 15/17}}}

recall that {{{sin(A)= opp/hyp}}}

so we know that {{{opp=15}}} and {{{hyp=17}}}

since {{{cos( A)=adj/hyp}}}, use {{{opp=15}}} and {{{hyp=17}}} to calculate {{{adj}}}side

{{{adj=sqrt(17^2-15^2)}}}
{{{adj=sqrt(64)}}}
{{{adj=8}}}

i)
then {{{cos( A)=8/17}}}

ii)  
{{{tan(A)=opp/adj}}}
{{{tan(A)=15/8}}}
