45° I think because 45° is half of 90° and no polygon interior angle is less than 90°
1 + 2 + 3 + 4 + 5 + 67 + 8 = 90
I think this is what you mean right?
The answer is 223.75 because you multiply 12.5 and 17.9
The formula for the surface answer 12cm
The answer is B, you know the zeros or solutions are positive 3 and 7 means no that they will be negative in the equation. And the parabola isn’t stretched or compressed so it doesn’t have a leading coefficient. Hope that helps!
