Trigonometry basic

Question

Hi,

 

1. How to solve triangle, if B=109,0mm (located sublevel), C=97,0mm (located on the right side) and γ= 32,9 degrees (located between left side A and sublevel B)?

 

2. Same positions but we know that A= 8,21m, b=7,13m and c=3,66m. What is (y) in degrees?

 

3. Same positions but we know that A= 61,2m, α= 41,4 degrees (located between C and B) and β= 38,1 degrees (located between A and C). What is B and γ?

 

4. Same positions but we know A= 24,9mm, B=40,8m and β=58,2 degrees. What is C and α?

Answer 1

I think you need to state the problem more clearly for us.  For example:

you have a triangle with vertices A, B and C and the sides opposite these angles are called a, b and c.

Now tell us which parts you have, and we can help you.

In general 2 sides and the included angle will be solved by the law of cosines.
