<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
