Answer:
14
Step-by-step explanation:
Since all of the side lengths are the same, angles across from each other are also the same.
Knowing that you can get the equation:
70=5x
To solve, you just divide 70 by 5, which gives you 14
I hope this simple calculation may help you.
Here,
5x+110°+110°+70°=360°
5x+290°=360°
5x=360°-290°
5x=70°
x=14°.
