I need help solving this question the first one says 3 options and they are 5,4,10 and the second one 60,180,360 and the last one is 360,1800,900

Answer 1

The polygon ABCDEFG is a heptagon, which is a seven-sided polygon. It can divided into 5 triangles.

The triangle sum theorem states that the sum of all interior angles in any triangle is equal to 180⁰

Therefore, the total interior angle measure of polygon ABCDEFG is:

$5\times180=900^{\circ}$
