Question

construct a quadrilateral pqrs in which PQ is 5 cm QR is price and angle P is equal to 60 degree angle Q is equal to 120 degree and Angle R is 90 degree measure angle s​

Answer 1

Answer:

angle s =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
