Question

I need to know how I get 65 degrees out of sin(.909) because sin of (.909)=.79 and sin^-1=1.14 and I do not have arcsin on my calculator 

9:38 AB =c = 12 ; AC =b; BC= a = 5 Applying pythagorous theorem in the given right angle triangle (Hypotenuse)? = (Base)2 + (Perpendicular)? c2 = a² + b² 122 = 52 + b² b2 = 144 -25 = 119 %3D %3D then b = V119 Step2 b) According to the given figure sinB = Perpendicular / Hypotenuse = b/c = V119/12 So, sinB = V119/ 12 = 10.90/12 = 0.9090 %3D B= sin'(0.9090) = 65.36º Answer %3D
