Cos C=(-49a^2-22)/(Sqrrt(49a^2+25)...

Cos C=(-49a^2-22)/(Sqrrt(49a^2+25))(Sqrrt(49...


Can you simplify this equation?


I think it's possible


If you can't see it, move your pointer over the 3 dots at the end


It's in a/bc form


Show work please!





From Eniram

Cos C=(-49a^2-22)/(Sqrrt(49a^2+25)...
lets say, a= -49a^2-22





b= sqrrt(49a^2+25)





c=sqrrt(49a^2+20)





lets square, a, b and c





a^2 = 2401a^4 + 484+1078a^2





b^2 = 49a^2+25





c^2 = 49a^2 +20





now lets calculate B^2*c^2=





2401a^4+2205a^2+500





hhmmm....... thought I could come up with something and cancel some stuff in the numerator and denominator, but nope.... I'm unable to go further
