Question

find the missing angle of the following polygons???
And please explain​

Answer 1

Answer:

A.T.Q

sum of all angles of a polygon = 360°------(i)

&

we have 2 angles are same.

then, let 1st missing angle be x

then 2nd missing angle is also = x

NOW,

=> x + x + 30° + 40 = 360° ----------(from i)

=> 2x + 70° = 360°

=> 2x = 360° — 70°

=> 2x = 290°

=> x = 290°/2

=> x = 145°

therefore, 1st missing angle = x = 145°

& also 2nd missing angle is also= x = 145°

Answer 2

Step-by-step explanation:

x + x + 30 + 40 = 360

2x + 70 = 360

2x = 360 - 70 =290

x = 290/2 = 185

hope it's help full for u : )
