Answer: x = 20
Step-by-step explanation:
A right angle adds up to 90 degrees. Therefore, the sum of all the angle values must equal 90
x + 2x + x + 10 = 90
4x + 10 = 90
4x = 80
x = 20
There are six important properties of parallelograms to know:
<span>Opposite sides are congruent (AB = DC).Opposite angels are congruent (D = B).Consecutive angles are supplementary (A + D = 180°).If one angle is right, then all angles are right.The diagonals of a parallelogram bisect each other.<span>Each diagonal of a parallelogram separates it into two congruent triangles.</span></span>
