Question

in the given five sided closed figure find angle ​

Answer 1

Answer:

as here three triangles are there . I.e. triangle ABC , AED , ACD.

total sum of the angles in a triangle is 180 degree..

hence sum of the angles of this five sided closed figure =3(180)

=540 degrees

Answer 2

$\angle ABC+\angle BCD+\angle DEA+\angle EAB+\angle CDE=540^{\circ}$

Step-by-step explanation:

The given closed figure have five sides.

We know that five sides closed figure is called pentagon.

Pentagon is a polygon.

We know that

Sum of angles of polygon=$(n-2)\times 180^{\circ}$

Where n=Number of sides of polygon.

Number of sides of given closed figure=n=5

Substitute the values then we get

$\angle ABC+\angle BCD+\angle DEA+\angle EAB+\angle CDE=(5-2)\times 180$

$\angle ABC+\angle BCD+\angle DEA+\angle EAB+\angle CDE=3\times 180$

$\angle ABC+\angle BCD+\angle DEA+\angle EAB+\angle CDE=540^{\circ}$
