This week, we have learned trigonometry and I will discuss one of the things I learned: the Sine Law.
It’s a very useful to solve any triangle as long as you have:
- an angle that has a side corresponding it.
- two angles / two sides / one angle and one side.
Here’s how it works: every angle needs to be written in CAPITAL LETTERS and every side needs to be written in LOWER CASE LETTERS.
angle A corresponds with side a or side BC.
angle B corresponds with side b or side AC.
angle C corresponds with side c or side AB.
what’s the formula?
if you’re finding an angle…
and if you’re finding a side…
