# What is the value of x? 14, 15, 16, 17

**Solution:**

The given figure is a __quadrilateral__.

The sum of all the interior angles of the quadrilateral is 360.

Therefore,

(5x)° + 110° + 110° + 70° = 360°

(5x)° + 220° + 70° = 360°

(5x)° + 290° = 360°

(5x)° = 360° - 290°

(5x)° = 70°

x = 70°/5

x = 14°

## What is the value of x? 14, 15, 16, 17

**Summary:**

The value of x in the given quadrilateral is 14°
