QUESTION 5

Answer 1

Answer:

900°

Step-by-step explanation:

The sum of interior angles of a polygon with $n$ sides is given by:

Sum = $(n-2)*180$

Here, the polygon has 7 sides, so $n=7$. Plugging this into the formula gives us:

Sum = $(7-2)*180\\=5*180\\=900$

So the answer is the first choice, 900°.
