Ответ:√2-2
Пошаговое объяснение:
sin(-7π/4)+cos(7π/4)+tg(15π/4)-ctg(-7π/4)=
(-sin(7π/4))+((cos(2π-π/4))+(tg(4π-π/4))+ctg(2π-π/4)=
sin(π/4)+cos(π/4)-tg(π/4)-ctg(π/4)=√2/2+√2/2-1-1=√2-2
<span>24610:4922+95*109-3*3385-2=
</span>1) 24610:4922 = 5
2) 95*109 = 10.355
3) 3*3385 = 10.155
4) 5+10.355-10.155-2=5+200-2=203
Если a+b 327 то надо отнять от 800-327=473
X = 32%
200 = 100%
x = (200*32%) / 100% = 6400 / 100 = 64
