Question

in a quadrilateral PQRS,angle P=120 and angle Q=angle R=angle S, find angle q, angle r and angle s​

Answer 1

We have,

∠P+∠Q+∠R+∠S=360

∘

100

∘

+∠Q+100

∘

+75

∘

=360

∘

∠Q=360

∘

−275

∘

=85

∘

Answer 2

Answer:

Given- P=120° Q=R=S=x

To find- x

we know sum of all angles of a quadrilateral is 360°

P+Q+R+S=360°

120+x+x+x=360

3x=360-120

x=240/3=80°
