Hey, learning about laws of sines problems. So when given 2 sides and an angle, after you go through the process, how do you conver a number to a sine? for example, one example on the website for my class is
7.7 over sin 43.2 degrees = 9.1 over sin B → sin B = 9.1 (sin 43.2 degrees) over 7.7 = 0.8090

→ B = 54° or B = 180° - 54° = 126° (to the nearest tenth
But how did they convert 0.8090 to sin 54/126?
