Answer:

12

Step-by-step explanation:

(5x+5)+(115)=180

180-120=60

60/5=12

Answer:

The value of x= 12.

Step-by-step explanation:

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

[tex]y+ 115^{\circ}=180^{\circ}[/tex]

By linear sum property

[tex]y=180-115[/tex]

By subtraction property of equality

We get y= [tex]65^{\circ}[/tex]

By simplification

[tex]5x+5=65^{\circ}[/tex]

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

[tex]5x=65-5[/tex]

By subtraction property of equality

5x=60

[tex]x=\frac{60}{5}[/tex]

By division property

x=12

Hence, the value of xis 12.
