When deriving the law of cosines, the equation h^2=a^2-x^2 is created using the pythagorean theorem. use substitution to replace h2 in the equation below and then simplify. c^2=h^2+b^2-2bx+x^2

A) c^2=a^2+b^2-2bx

Step-by-step explanation:

got it right on edge :)

Step-by-step explanation:

We are given equation

we need to plug this equation into

we can replace h^2

and we get

now, we can cancel like terms

so, we get after simplification as

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz
