What I learned this week- Trig
categories: Math 10
This week in trigonometry I learned how to find the angle in a triangle with only having two side lengths.
If this is your triangle:
First you would have to label it using Hypotenuse, opposite, and adjacent.
-Hypotenuse goes across for the right angle
-Opposite goes across from the angle your trying to find
-Adjacent goes wherever opposite doesn’t go
Then you have to use SOH CAH TOA to find the angle
In this case I would use cosine because the triangle has the side lengths adjacent and hypotenuse.
You would type this into your calculator
The answer is 62 degrees
