1 answer:
The length of the fourth side of the quadrilateral is 2.2 cm. Then the correct option is B.
<h3>What is a quadrilateral?</h3>It is a polygon that has four sides. The sum of the internal angle is 360 degrees.
A quadrilateral so that three of its four sides measure 3 centimeters each.
The angles between these sides have measures of 80° and 85°.
The following procedures are to draw the diagram will be
- Make a line of 3 cm.
- Draw the lines of 3 cm each from the terminal points of the first line at 80° and 85°.
- join the terminal point of the second and third lines.
- The required quadrilateral is formed.
The length of the fourth side of the quadrilateral is 2.2 cm
Thus, the correct option is B.
