ANSWER

(a)

Sum of all interior angles of quadrilateral =360

0

∴50+130+120+x=300

x=60

0

(b)

90+a=180

a=90

Sum of all angles of quad =360

x+70+60+90=360

x=140

0

(c)

70+a=180 (Linear pair)

a=110

60+b=180 (Linear pair)

b=120

Sum of measures of all angles of pentagon =540

0

∴120+110+x+x+30=540

2x=280

x=140
