Step-by-step explanation:
sec A = cot A , means 1/cos A =1/tan A
1/cos A = cos A/sin A
cross multiplication
cos^2 A =sin A ( cos^A =1–2 sin^2 A )
2 sin^2 A - sin A -1 = 0
then use the calculator to solve this equation : 2 x^2 - x -1=0
so x will be - 0.5 or 1
so A = sin^-1(-0.5) =120 or sin^-1(1)=90
finally.
