Two interior angles on the same side of a transversal that cuts two parallel lines are
(
7
x
−
5
)
∘
(7x - 5)^\circ
(
7
x
−
5
)
∘
and
(
3
x
+
25
)
∘
(3x + 25)^\circ
(
3
x
+
25
)
∘
. Which one of the following equations will give the correct value of
x
x
x
? a)
(
7
x
−
5
)
+
(
3
x
+
25
)
=
90
(7x - 5) + (3x + 25) = 90
(
7
x
−
5
)
+
(
3
x
+
25
)
=
90
b)
(
7
x
−
5
)
+
(
3
x
+
25
)
=
180
(7x - 5) + (3x + 25) = 180
(
7
x
−
5
)
+
(
3
x
+
25
)
=
180
c)
7
x
−

=
3
x
