Answer 1

• 4/5 or 0.8

----------------------

Find the hypotenuse using Pythagorean theorem:

• 
  `c=√(a^2+b^2) =√(3^2+4^2)=√(25)=5`

If θ is the smallest angle, then opposite side of this angle is the smallest leg, 3 units and therefore adjacent leg is 4 units.

Find cos θ:

• cosine = adjacent / hypotenuse
• cos θ = 4/5 or 0.8
