The measure of ∠E is 51 degrees.
What is the sum of the internal angles of a quadrilateral?
The sum of the internal angles of a quadrilateral is 360 degrees.
We can find the value of the unknown angle as shown below:
The angles are given as 89, 130, and 90 degrees. The sum of the angles of a quadrilateral is always 360 degrees.
This means that:
∠E + 89° + 130° + 90° = 360°
∠E = 360° - 89° - 130° - 90°
= 360° - 309°
= 51 degrees.
The value of the angle E is 51 degrees.
Therefore, we have found the measure of ∠E to be 51 degrees.
