A key word to remember when doing this type of math is "SOHCAHTOA".

Sine =

Opposite over

Hypotenuse

Cosine =

Adjacent over

Hypotenuse

Tangent =

Opposite over

Adjacent


Since this is a 3, 4, 5 triangle, with the sides just multiplied by 7, the opposite of A which is 28 would be simplified to 4.

And the Hypotenuse would be simplified to 5.

So, the answer is 4 / 5!
