Answers:

A, B, D, E

Nearly everything except choice C is true.

====================================================

Step-by-step explanation:

  • Choice A is true because sine = opposite/hypotenuse.
  • Choice B is true as well because cosine = adjacent/hypotenuse
  • Tangent is opposite/adjacent. The 4/9 should be 9/4. Therefore, choice C is false. If beta was theta, then tan(theta) = 4/9 would be true.
  • Choice D is true because of the pythagorean theorem a^2+b^2 = c^2.
  • Choice E is true because tan = opposite/adjacent, and the 9 and 4 are in the correct order (see choice C).
