Answer 1

Answer:

pls attach the figure n repost

Answer 2

Step-by-step explanation:

(a)

(a)Sum of all interior angles of quadrilateral =360°

∴50+130+120+x=300

∴50+130+120+x=300x=60°

(b)

(b) 90+a=180

(b) 90+a=180a=90

(b) 90+a=180a=90Sum of all angles of quad =360

(b) 90+a=180a=90Sum of all angles of quad =360x+70+60+90=360

(b) 90+a=180a=90Sum of all angles of quad =360x+70+60+90=360x=140°

(c)

(c) 70+a=180 (Linear pair)

(c) 70+a=180 (Linear pair)a=110

(c) 70+a=180 (Linear pair)a=11060+b=180 (Linear pair)

(c) 70+a=180 (Linear pair)a=11060+b=180 (Linear pair)b=120

(c) 70+a=180 (Linear pair)a=11060+b=180 (Linear pair)b=120Sum of measures of all angles of pentagon =540 °

∴120+110+x+x+30=540

∴120+110+x+x+30=5402x=280

∴120+110+x+x+30=5402x=280x=140°

(d)

(d) Sum of all angles of pentagon 540

(d) Sum of all angles of pentagon 540Given all angles are equal

(d) Sum of all angles of pentagon 540Given all angles are equal∴5x=540

(d) Sum of all angles of pentagon 540Given all angles are equal∴5x=540x=108°
