Answer:
Using the Half Angle Formula:
sin
2
(
x
)
=
1
2
[
1
−
cos
(
2
x
)
]
with
x
=
15
°
and
2
x
=
30
°
you get:
sin
2
(
15
°
)
=
1
2
[
1
−
cos
(
30
°
)
]
knowing that:
cos
(
30
°
)
=
√
3
2
:
sin
2
(
15
°
)
=
1
2
[
1
−
√
3
2
]
sin
2
(
15
°
)
=
2
−
√
3
4
=
0.067
So:
sin
(
15
°
)
=
±
√
0.067
=
±
0.258
We choose the positive one.
