The measure of angle CED is y. The correct option is the second option- y, because Triangle ABC is <u>similar</u> to triangle EDC
<h3>Similar triangles </h3>
From the question, we are to determine the measure of angle CED
In the diagram, we can observe that ΔABC is <u>similar</u> to ΔEDC
This is by the Angle-Angle similarity theorem
The theorem states that
If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other
Thus,
Angle CAB = Angle CED
In the diagram,
Angle CAB = y
∴ Angle CED = y
Hence, the measure of angle CED is y. The correct option is the second option- y, because Triangle ABC is <u>similar</u> to triangle EDC
