Answer: The value of b is 22.62

Step-by-step explanation: 20 is the opposite of b, 52 is the hypotenuse. Because we're given the opposite and hypotenuse, we have to use sine. So....

sin b=20/52

sin b = 0.38461538461

then using inverse of sine, the equation would be sin^-1(0.38461538461)

by putting that into the calculator you get 22.61986495 (aka 22.62)
