Answer:

The value of x= 12.

Step-by-step explanation:

Given two parallel lines b nd c are crossed by a transversal  line 'a'.

y+ 115^{\circ}=180^{\circ}

By linear sum property

y=180-115

By subtraction property of equality

We get y= 65^{\circ}

By simplification

5x+5=65^{\circ}

b and c are parallel lines and cut by transversal line a then alternate interior angles are equal.

5x=65-5

By subtraction property of equality

5x=60

x=\frac{60}{5}

By division property

x=12

Hence, the value of xis 12.
