Respuesta :

opposite angles of parallelogram are equal.
sum of interior angles of parallelogram is 360 degrees.

Therefore,
A + B + C + D = 360
x + 145 + x + 145 = 360 
x = 35
Therefore angle C is 35 degrees 

The measure of angle C is 35 degrees .

What is a parallelogram?

That quadrilateral in which opposite sides are parallel is called a parallelogram.

WE know that the property of parallelogram;

The opposite angles of parallelogram are equal.

The sum of interior angles of parallelogram is 360 degrees.

Given that parallelogram ABCD and angle D = 145 degrees

Therefore,

A + B + C + D = 360

x + 145 + x + 145 = 360

x = 35

Hence, angle C is 35 degrees .
