$\displaystyle\bf 1)\\3Sin\frac{\pi }{6} +2Cos\frac{\pi }{6} -tg\frac{\pi }{3}= 3\cdot\frac{1}{2} +2\cdot\frac{\sqrt{3} }{2} -\sqrt{3} =1,5+\sqrt{3} -\sqrt{3} =1,5\\\\\\2)\\5Sin\frac{\pi }{4} +3tg\frac{\pi }{4} -5Cos\frac{\pi }{4} -10Ctg\frac{\pi }{4} =5\cdot\frac{\sqrt{2} }{2} +3\cdot 1-5\cdot\frac{\sqrt{2} }{2}-10\cdot 1=\\\\=3-10=-7$
