given
<p=<q
<r=<s
and <p=2<r
by angle sum property of quadrilateral
<p+<q+<r+<s=360
2<r+2<r+<r+<r=360
<r=360/6
=60
hence each angle measures
<p=120=<q
<r=60=<s
<p=<q
<r=<s
and <p=2<r
by angle sum property of quadrilateral
<p+<q+<r+<s=360
2<r+2<r+<r+<r=360
<r=360/6
=60
hence each angle measures
<p=120=<q
<r=60=<s

∠P = 120 ° , ∠Q = 120 ° , ∠R = 60 ° and ∠S = 60 °
Step-by-step explanation:
Given ,
∠P = ∠Q, ∠R = ∠S and ∠P = 2∠R
To find, the measure of each angle = ?
By angle sum property of quadrilateral ,
∠P + ∠Q + ∠R + ∠S = 360 °
⇒ ∠P + ∠Q + ∠R + ∠S = 360 °
⇒ 2∠R + 2∠R + ∠R + ∠R = 360 °
⇒ 6∠R = 360 °
⇒ ∠R =60 °
∴ ∠P = ∠Q = 2 × 60 ° = 120 ° and
∠R = ∠S = 60 °
Hence, ∠P = 120 ° , ∠Q = 120 ° , ∠R = 60 ° and ∠S = 60 °.
