Question

find the missing angles of the following polygons

Answer 1

Answer:

(c) i). X = 60- 180 (linear pair)

X= 120

ii) y = 180-70 ( linear pair)

y = 110

( iii) z = w

( z+w)+x+y=360

2w + 120+ 110 = 360

2w = 360-230

2w = 130

w = 65

Answer 2

Answer:

In figure c) x=120, y=110

Step-by-step explanation:

you can find x and y using linear pair.

as for z and w,

120+110+w+z=360

as w and z are equal,

120+110+w+w=360

230+2w=360

2w=360-230

2w=130

w=65

since w=z, z also =65

...

you can do the rest of them in a similar manner.

hope it helps !
