Answer:
If
θ
were in Q1 then we would simply be dealing with the internal angles of a
5
,
12
,
13
right angled triangle.
Note that:
5
2
+
12
2
=
25
+
144
=
169
=
13
2
Hence in Q1 we would have:
sin
θ
=
12
13
and
tan
θ
=
12
5
In Q2,
cos
θ
<
0
, so cannot be equal to
5
13
, so there is an error in the question.
In Q4, we would find
sin
θ
=
−
12
13
and
tan
θ
=
−
12
5
.
