Answer:
Each angle within that right angle measure 45 degrees.
Step-by-step explanation:
Given:
The two pieces of furniture forms Right angle
The Right angle is bisected by another bar
To Find:
what would each angle measure within that right angle = ?
Solution:
The Two furniture are attached such that the ange betwwn them is right angle.
The right angle measures 90 degrees
Then an another bar bisects this right angle.
The word bisects means divided into two equal halves
so bisecting the right angle means, bisecting 90 degrees
=> ![\frac{90}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B90%7D%7B2%7D)
