sin²θ = 0.75
we know that,
sin²θ + cos²θ = 1
0.75 + cos²θ = 1
cos²θ = 1-0.75 = 0.25
we know that,
sin²θ + cos²θ = 1
0.75 + cos²θ = 1
cos²θ = 1-0.75 = 0.25

sin square theta equals=0.75
we know sin sqare theta=1-cos square theta
0.75=1-cos square theta
or, cos square theta=1-0.75
or, cos square theta=0.25
we know sin sqare theta=1-cos square theta
0.75=1-cos square theta
or, cos square theta=1-0.75
or, cos square theta=0.25
