Answer:

Sin A = 16/20

Cos B = 12/20

tan A =16/12

Step-by-step explanation:

sin is defined as


\sin A=(opposite)/(hypotenuse)

Now the side opposite to angle A measures 16 and the hypotenuse measures 20; therefore,


\sin A=(16)/(20)

Similarly,


\cos A=\frac{\text{adjacent}}{hypotenuse}

since for angle A adjacent = 12 and hypotenuse = 20, the above gives


\cos A=(12)/(20)

Finally, the tangent ratio gives


\tan A=(opposite)/(adjacent)

since opposite = 16 and adjacent = 12, the above gives


\tan A=(16)/(12)

Hence, to summerize ur results
