Question

Chapter 3.5, Problem 21WE

To determine

Find the value of x.

Expert Solution & Answer

Answer to Problem 21WE

The value of x is 60° and sides AD and BC must be parallel.

Explanation of Solution

Given information :

The given quadrilateral ABCD whose measure of angles are m∠A=x,m∠B=2x,,m∠C=3x, and m∠D=4x,

The sum of interior angles of a quadrilateral is 360°

So,

m∠A+m∠B+m∠C+m∠D=360°x+2x+3x+4x=360°10x=360°x=360°10=60°

Hence, the value of x is 60°

And

m∠A=60°,m∠B=120°,,m∠C=180°, and m∠D=240°

Since

m∠A+m∠B=60°+120°=180°

Therefore, the pair of sides are AD and BC must be parallel.
