We cannot draw any quadrilateral with these angles. So, we cannot find the longest side.
Step-by-step explanation:
Given,
The angles of AQRS are
m∠Q = 80°
m∠R = 65°
m∠S = 35°
We know that the sum four angles of a quadrilateral is 360°
According to the problem,
∠A+∠Q+∠R+∠S =360°
or, ∠A = 360° - (80°+65°+35°) [ by putting the values of the angles]
or, ∠A = 180°
As per the calculation we cant draw any quadrilateral of having an angle of value 180°. So we cannot find the longest side.
