<h3>The measure of third angle of triangle is 67 degrees</h3>
<em><u>Solution:</u></em>
Given that,
The support of a wood table are in the shape of a right triangle
Since it is a right angle, one of the angle must be 
The measure of one of the angles is 23 degrees
To find: third angle angle
We know that,
Sum of all angles in triangle equals 180 degrees
Therefore,

Thus measure of third angle of triangle is 67 degrees
The solid 3D object that is produced by rotating the triangle about line m is a cone.
<h3>What is a triangle?</h3>
It should be noted that a triangle simply means a shape that has three sides and three angles.
In this case, the solid 3D object that is produced by rotating the triangle about line m is a cone.
