Answer:

4/5

Step-by-step explanation:

In a right triangle, the longest side is always the hypotenuse. Hence

Hypotenuse =5cm

The side opposite to the angle theta is the opposite, hence

Opposite = 4cm

Required

Sin theta

According to SOH CAH TOA

Sin theta = opposite/hypotenuse

Sin theta = 4/5

Hence the sine of the angle opposite the side of length 4cm is 4/5
