2. one?... ABC ... are you sure thats the whole question?
5. plug in arcsin4/7 (arccos2/5, etc...)into yer calculator...
2.In triangle ABC, B=65 degrees, b=2 and c=12. How many triangles are possible?
3. Find sin29°42' to four decimal places_
4. Find sec17°8'49" to four decimal places
5.Which of the following statements would give the largest value of theta if theta was less then 90°?
I tried to put number 3 and 4 into a caluculator but the answers were wrong.
I converted (5) to sintheta=4/7 etc, costheta=2/5.. but I don't know how to finish from there
I am completely lost at number 2
Did you make a sketch?2.In
How many triangles are possible?
If such a triangle were possible, it might look like this:
Code:C * / \ / \ / \ / \ 2 / \ / \ / 65° \ B * - - - - - - - * A 12
Law of Sines: .
So we have: .
Then: . . . . which does not exist.
Therefore, it is no triangle.
