EXPLANATION
Given the triangle on the circle, we can see that the angle A is a 90 degrees angle, so we can apply the Law of Sines as shown as follows:
Law of Sines:
In this case, A= 23sqrt(2), Sin A= Sin 90 = 1, B=x , Sin B = Sin 45
Replacing terms:
Switching sides:
Multiplying both sides by Sin 45:
Solving Sin 45:
Applying the square root properties and grouping the fractions:
Simplifying the square root with the power:
The answer is x=3
