According to this diagram, what is cos 16?

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

because that’s us why

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
