Can someone find this angle?

​

area of the given heptagon is 54 square units.

It is a polygon having 7 sides.

coordinates  of all 7 vertices are given as:

(-5,3)

(-4,5)

(-2,3)

(3,4)

(4,3)

(4,-3)

(-3,-3)

in the uploaded diagram. heptagon has been split into 5 triangles, called T1, T2, T3, T4, and T5.

Now the area of the heptagon= T1+T2+T3+T4+T5

AreaT1= 3*2/2=3

AreaT2= 3*6/2=9

AreaT5=6*7/2=21

AreaT3=14.5, Using the coordinate formula for the area of a triangle.

AreaT4=6.5,  Using the coordinate formula for the area of a triangle.

Total Area= 3+9+21+14.5+6.5= 54

hence, the area of the given heptagon is 54 square units.
