\left(\sin ^{-1} x\right)^2+\left(\sin ^{-1} y\right)^2+2 \sin ^{-1} x \sin ^{-1} y=\pi^2

, then

x^2+y^2

is equal to:

View answer and explanation

Correct option: C

Option C (2) is correct because the given equation can be simplified to find the values of x and y, and then

x^2 + y^2

can be calculated.
