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:


(A)/(\sin A)=(B)/(\sin B)

In this case, A= 23sqrt(2), Sin A= Sin 90 = 1, B=x , Sin B = Sin 45

Replacing terms:


\frac{23\sqrt[]{2}}{1}=(x)/(\sin 45)

Switching sides:


(x)/(\sin 45)=23\sqrt[]{2}

Multiplying both sides by Sin 45:


x=\sin 45\cdot23\cdot\sqrt[]{2}

Solving Sin 45:


x=\frac{\sqrt[]{2}}{2}\cdot3\cdot\sqrt[]{2}

Applying the square root properties and grouping the fractions:


x=(3)/(2)\sqrt[]{(2)^2}

Simplifying the square root with the power:


x=(3)/(2)\cdot2=3

The answer is x=3
