Answer: Hello mate!

Here we have a triangle rectangle, there is a very useful relation and mnemotechnic:

So-ca-toa:

this mean:

Sen(a) = (opposite cath)/hypotenuse

cos(a) = (adjacent cath)/hypotenuse

tan(a) = (opposite cath)/(adjacent cath)

now we want to know the value of cos(16°)

we know that the hypotenuse has 25 units, and the adjacent cathetus to the 16° angle has a length of 24 units.

then; cos(16°) = 24/25 = 0.96
