1. Two angles of a quadrilateral measure 140° and 80°. T1. The other two angles are in a ratio of 3:4. What is the value of x? What are the measures of those two angles? x =
2.Next, list the measures of the other two angles from lowest to highest.

Angles are 3x, 4x =

Angles from lowest to highest:

Step-by-step explanation:

Given:  Two angles of a quadrilateral measure 140° and 80°. The other two angles are in a ratio of 3:4.

To find: value of x, measures of those two angles and

Also, to list the measures of the other two angles from lowest to highest.

Solution:

According to angle sum property of a quadrilateral, sum of angles of a quadrilateral is 180°.

Let the two angles be 3x and 4x

So, angles are as follows:

Angles from lowest to highest:
