    so sin x=8/17. cos x=sqrt(1-xin^2 x)=sqrt(1-64/289)=sqrt(225/289)=-15/17. as it is given cos x is negative. so, sec x=1/cos x=-17/15

    I don't understand what the final answer is for #1. Is it (-17/15) ?

    #1 \[\cos \Theta\] =-15/17 \[\sec \Theta\] =-17/15 #2 \[\sin(\tan^{-1} (1)=\] \[\sin 45 =\] \[\sqrt{2}/2\] #3 \[6(1/\sqrt{3})-2(-\sqrt{3}/2)\] \[6(\sqrt{3}/3) + \sqrt{3}\] \[2\sqrt{3} + \sqrt{3}\] \[3\sqrt{3}\] #4 tan 35 = a/10 tan 62 = b/10 a = 0.7002*10 b=1.8807*10 a = 7.002 b = 18.807 Distance between towns is: 18.807-7.002 ans: 11.805
