Answer:
Step-by-step explanation: we will first work out a
so 23 is the hypotenuse
a is the opposite
so what we need to do is 46sin(23) and that will give you 17.97 cm
next we will work out b
b is the adjacent
23 is the hypotenuse
so in this case we must do 46cos(23) and that will give you 42.34
last, we will work out B
a is 17.97 cm and its the adjacent
23 is the hypotenuse
so we do sin-1(17.97/23)= 51.38
