Solution:
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 [tex]90^{\circ}[/tex]
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,
[tex]90^{\circ} + 23^{\circ} + \text{ third angle } = 180^{\circ}\\\\ \text{ third angle } + 113 = 180\\\\ \text{ third angle } = 180 - 113\\\\ \text{ third angle } = 67^{\circ}[/tex]
Thus measure of third angle of triangle is 67 degrees
