uh, not quite which side is adjacent to A?

  • Vocaloid
that's the hypotenuse, try again

@Vocaloid 24?

nope, try again... adjacent means the side next to the angle, NOT including the hypotenuse

see how "opposite" is on the opposite side of the triangle? see how "adjacent" is next to A but NOT the hypotenuse? see how the hypotenuse is the longest side? so, if cos(A) = adjacent/hypotenus, what is cos(A)?
DJ3strella
  • DJ3strella
yes

so, what is cos(A)?

AB is opposite to C and AC is adjacent to C, right? we know that tan(C) = opposite/adjacent, so tan(C) = 4/9 solve for C
