Find the supplement of an angle with the given measures.

Mathematics
1 answer:
Mumz [18]4 years ago
4 0
The supplement of an angle will be its difference from 180° (or -180°). Hence your supplements are
.. -37° ⇒ -143° or 217°
.. -9° ⇒ -171° or 189°
.. -84° ⇒ -96° or 264°

Since you allow angles to be negative, I'd probably choose the negative value as the supplement.

_____
If you're going to define angles in such a way as to allow their measures to be negative, then you need to make a corresponding definition of complement and supplement. One definition I've seen of "supplement" is that it meets the requirements that
.. sin(θ) = sin(supplement(θ))
.. cos(θ) = -cos(supplement(θ))

The above angles (either positive or negative) will meet these requirements.

Answer:

  a=\sqrt{33}

Step-by-step explanation:

The Pythagorean theorem tells you that the area of the square with side 'a' is the difference of the areas of the other two squares.

  a² = 7² -4²

  a² = 49 -16 = 33

  a = √33
