Question

first solve it, find the sum of a, b, c, d, e, f, g, h in Given figure

Answer 1

180 × 4 - 360°

720 - 360°

= 360°

Answer 2

Answer:

Correct option is B

Step-by-step explanation:

Sum of interior angles of an n sided polygon = (2n−4)×90 degrees.

Let us find the sum of the interior angles of a this quadrilateral with 4 sides.

⇒n=4

Sum of interior angles of a heptagon =(2×4−4)×90

⇒4×90⇒=360

⇒360  

One angle of a quadrilateral= 360/4=90

So by vertically opposite pairs, one angle of triangle is also 90.

There are 4 triangles,

So  sum= 90X4= 360.
