Sin x = opphyp\frac{opp}{hyp}hypopp
sinx = 35\frac{3}{5}53
using Pythagoras' theorem
hyp2^{2}2 = opp2^{2}2 + adj2^{2}2
adj2^{2}2 = 52^{2}2 - 32^{2}2 = 25 - 9
adjoppadj\frac{opp}{adj}adjopp = 16
adj = √ 16
adj = 4.
tanx = 34\frac{3}{4}43
= adjhyp\frac{adj}{hyp}hypadj
cosx = 45\frac{4}{5}54
= 34\frac{3}{4}43
(tanx + 2cosx) = 45\frac{4}{5}54 + 2(15+3220\frac{15+32}{20}2015+32)
= 4720\frac{47}{20}2047
= 720\frac{7}{20}207 or
2 1120\frac{11}{20}2011
