Answer 2

Answer:

80

Step-by-step explanation:

we get measures of 3 angles of quadrilateral by linear pair angles

so find out them,

PQR=180-80=100°

QPS=180-70=110°

PSR=180-130=50°

sum of all angles of quadrilateral is 360°.

PQR+QPS+PSR+QRS=360

100+110+50+QRS=360

260+QRS=360

QRS=360-260

QRS=100

x is linear pair angle of QRS

QRS+x=180

100+x=180

x=180-100

x=80
