Answer: sin(60°)=
\frac{√(3)} 2 and cos(60°)=
\frac{1} 2

Step-by-step explanation:

sine means opposite/hypothenus (SOH)

opposite=
\frac{√(3)} 2 and hypothenus is 1

sin(60°) =
\frac{√(3)} 2 ÷
\frac{1} 1

=
\frac{√(3)} 2 ×
\frac{1} 1

=
\frac{√(3)} 2

cosine means adjacent/hypothenus (CAH)

adjacent=
\frac{1} 2 and hypothenus is 1

cos(60°) =
\frac{1} 2\\ ÷
\frac{1} 1

=
\frac{1} 2 ×
\frac{1} 1

=
\frac{1} 2
