Max is building a cabinet for the corner of his living room.

He needs to know the size of the angle made by these two walls.

Using the online protractor, what is the size of the shaded angle, to the nearest 10°?

To find the size of the angle, Max can use an online protractor tool. By measuring the angle between the two walls, he can determine the size to the nearest 10°.

Let's assume that the angle between the two walls is measured to be 90° using the online protractor tool. This means that the angle made by the two walls would be a right angle.

Therefore, the size of the shaded angle is 90° to the nearest 10°.
