Answer:

900 degrees

Step-by-step explanation:

So what you do is find how many triangles there are in a shape by counting the number of sides.

This has 7 sides.

So you use the formula 180(n - 2) to find the sum of all interior angles and to find the number of triangles in a shape.

180(7 - 2)

7 - 2 = 5

They're 5 triangles in a heptagon.

180(5) = 900

So the final answer is 900 degrees.
