Answer:

We know sum of all sides of quadrilateral is 360°

using the same concept,

110 + 70 + 110 + x = 360

290 + x = 360

x = 70°

now x is 70 , therefore quadrilateral is parallelogram since parallelogram has equal opposite angles..

Answer:

x = 70

parallelogram

Step-by-step explanation:

x is equal to 70 because the opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure. \

Classify the quadrilateral:
