The interior angles formed by the sides of a quadrilateral have measures that some to 360°

Molodets [167]

Answer:

Value of x is 34

Step-by-step explanation:

The figure is a quadrilateral;

Angles given are; 2x°, 88°,108° and (3x - 6)°

We already know that the interior angles of a quadrilateral add up to 360°

Therefore, to get the value of x;

2x° + 88° + 108° + (3x - 6)° = 360

5x° + 190° = 360°

5x° = 170°

x = 34°

Thus, the value of x is 34
