Sagot :

Answer:

sin 60 = √3/2

means perpendicular (p)= √3

and

base (h)=2

find base(b)

using pythagoras theorem

h²=p²+b²

than base (b) will be 1

now

cos 60 =b/h

=1/2

Answer:

cos 60° = 1/2

  • Sin = opposite/hypotenuse
  • Cos = adjacent/hypotenuse
  • Tan = opposite/adjacent

sin 60° = opposite / hypotenuse

sin 60° = √3 / 2

The bottom side = √3, the hypotenuse = 2

To find the right side's value, you use Pythagorean's Theorem

  1. a² + b² = c²
  2. a² + (√3)² = 2²
  3. a² + 3 = 4
  4. a² = 4 - 3
  5. a² = 1
  6. a = 1

cos 60° = adjacent/hypotenuse

cos 60° = 1 / 2
