Trigonometry Solving a Right Triangle

2
Solving a Triangle.. …means to determine all the lengths and angles based on a few known values

3
Recap- Solving a triangle If we know sides In this case, we know Sin C = opp = 8 Ahyp 10 = 0.8 8 10 B6 C If we know angles and sides In this case we know Sin 53° = opp = AB A hyp 10 10 Sin 53°= AB 10 (0.7986…)= AB 10 8=AB B 53° C

4
But… In this case, Sin C = opp = 8 Ahyp 10 = 0.8 8 10But then all we know is that Sin C= 0.8… B6 C That didn’t give us our angle…

5
So! New calculator trick In this case, Sin C = opp = 8 Ahyp 10 = 0.8 8 10 Sin C= 0.8 (Sin -1 ) Sin C= (Sin -1 ) 0.8 C= (Sin -1 ) 0.8 B6 C C= 53.13°
