Question 80521: I have a TI-30XA calculator. I have the following problem to solve and can't seem to make it work with the Calculator. If could give me step by step using this calculator to solve this I would very much appreciate it.
Problem:
"Find the measure of the acute angle that satisfies the given equation. Round your answers to the nearest tenth of a degree"
1. tan A=3/4
2. tan B=13/7
3. tan C=3.123
4. tan C=0.9714
Thanks for your Help,
Mateo

Hello Mateo,
Before I go into the specifics, I'd like to know if you are:
1) using the Tan Inverse function on your calculator.
For example, when you are calculating for angle A for #1, you should be inputting "tan^-1 (tan to the power of -1), then 3/4 or 0.75.
If you are not doing this, this is why you are not getting the angle measures.
2) in Degrees mode
Please go to MODE on your calculator and see if you are in Radian or Degree.

However, if you have been following these two steps, please write back so I can do my best to solve your problem.
