Week 7- Math 10

The most fun and interesting part of this week was learning how to find missing angles using sin, cos and tan on my calculator.

If I had a question like this (I labeled each side already and written SOH CAH TOA to figure out which one to use):

Just having sin, cos or tan would not be helpful because I am not given the degree of the angle inside. Instead, I would use each of those to the power of -1. Since I now know which sides I’m given and which formula to use, I can start to write my equation and solve it, like so:
