- Hey! It's me, Yll and I am here to show you my math Trigonometry comic strip!
- 37 degrees
- Boards are measured by their diagonal distance. We can find their width using trigonometry.
- 15 feet
- The diagonal (hypotenuse) is 15 feet long. The angle given is 37 degrees. Therefore to find the width, we do cosine(37) times 15 to find the width is approximately 12.0 feet long!

- The angle of elevation is 52 degrees, the shadow (adjacent side) is 23 feet and I want to know the height (opposite side)To do so, I will take tan(52) and multiply it by 23. I found out the locomotive is 29.4 feet tall!
- When I was little, I always liked trains so we will take a train as an example! I want to find the height of this locomotive using its shadow.
- 52 degrees
- 23 feet

- I have been painting my house. I had to figure out a safe angle for my ladder to make with the floor when I lean it up against the wall.
- A safe ladder makes a 75 degree angle with the floor. Will my ladder be safe or not?
- ??
- 2 feet
- 8 feet
- We must use inverse trig to find angle measures. Since we have the opposite (8 feet) and adjacent (2 feet) sides, we use tangent.So tan^-1 (8/2) = 76 degreesClose enough! I won't die. :)
