Question

find trigonometric ratio of -90​

Answer 1

Answer:1 - The sine of angle A = sin (A) = side opposite angle A / hypotenuse = a / c

2 - The cosine of angle A = cos (A) = side adjacent to angle A / hypotenuse = b / c

3 - The tangent of angle A = tan (A) = side opposite angle A / side adjacent to angle A = a / b

4 - The secant of angle A = sec (A) = hypotenuse / side adjacent to angle A = c / b

5 - The cosecant of angle A = csc (A) = hypotenuse / side opposite to angle A = c / a

6 - The cotangent of angle A = cot (A) = side adjacent to angle A / side opposite angle A = b / a
