Answer:
Step-by-step explanation:
tanx + cotx = secx / sinx
take left hand side
=tanx + cotx
=sinx/cosx + cosx/sinx
=sinx*sinx+cosx*cosx/sinx*cosx
=sin^2x + cos^2x/sinx*cosx
=1/sinx*cosx
=1/cosx * 1/sinx
=secx/sinx
at second last step i changed multiplication sign into divide sign and write the reciprocal of 1/sinx which is sinx.

Answer:
3.5
Step-by-step explanation:
5(6-x)=12.5
(5*6)-(5*x)=12.5
30-5x=12.5
subtract 30 from each side:
-5x=-17.5
divide -5 from each side:
x=3.5
