Ответ:
x^2 - x - 2 = 3x - 4
x^2 - x - 3x - 2 + 4 = 0
x^2 - 4x + 2 = 0 ;
is the quadratic formula ;
a = 1 ; b = -4 ; c = + 2 ;
The solutions are ( - 1 +
Ответ:
sinx=p/h -----> some people have
cosx=b/h ----> curly brown hair
tanx=p/b -----> through proper brushing
easy way to remember it
we need cos c for this
h= 26 which is always the longest side of the triangle
b= 10
p=24
these both can be switched depending on which angle the question is talking about in this case its angle C so 10 is the base, if it was angle a 24 would have been the base
