Question

Q 12(i) & (iii) Find The angle measure X in the following

Answer 1

ello... dear...❤️

In figure I:-

40° + 140° + 100° + x = 360°

280° + x = 360°

x = 360° - 280°

x = 80°

In figure III:-

90° + 110°+ 60° + x = 360°

260° + x = 360°

x = 360° - 260°

x = 100°

Hope it helps uhhh...❤️

Answer 2

Step-by-step explanation:

12 (i)

x + 140 + 100 + 40 = 360 (sum of all angles of a quadrilateral

x + 280 = 360

x = 360 - 280

x = 80°

12 (iii)

90 + 110 + 60 + x = 360 (sum of all angles of a quadrilateral)

260 + x = 360

x = 360 - 260

x = 100°
