Answer
Angle RHO = 134°
Step-by-step explanation
To answer this, we need to just point out that the diagonals divide each of the corner angles into two equal parts.
And we can see that
Angle RHO = Angle 5 + Angle 6
But since the diagonal divides that corner angle into two equal parts,
Angle 6 = Angle 5 = 67°
Angle RHO = Angle 5 + Angle 6
Angle RHO = 67° + 67° = 134°
Hope this Helps!!!
