Question

Construct a qualideteral PQRS in which PQ=QR= 5cm, RS= 6cm, and angle Q=120 degree and angle R=60 degree ​

Answer 1

Answer:

80

Step-by-step explanation:

in a quadrilateral sum of all angles is 360

angle p+ angle Q+ angle R+ angle S=360

60+120+90+angle s=360

270+angle s=360

angle s=360-270=80
