Question

Classify the quadrilateral and find the value of x

Answer 1

x = 70

parallelogram

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:

parallelogram

It is a parallelogram because it has two pairs of parallel sides.

Answer 2

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..
