sin A = cos B (option 1)
Explanation:
angle C = 90°
Using sine ratio:
sin A = opposite/hypotenuse
opposite = side opposite angle A = 12
hypotenuse = 13
sin A = 12/13
Using cosine ratio:
cos B = adjacent/hypotenuse
opposite = side opposite angle = 5
adjacent = 12
hypotenuse = 13
cos B = 12/13
sin A = cos B = 12/13
The correct statement is sin A = cos B (option 1)
