"If they cancel school, then it rains."
300
Whether the lengths of 7.3 cm, 5.02 cm and 2.1 will form a triangle
What is no, they will NOT form a triangle because the sum of the 2 shortest sides is less than the third side.
300
The sum of the exterior angles in an n-gon.

300
two parts: a) what a regular polygon is. b) the measure of one interior angle of a 15-gon polygon

400
The slope of a line perpendicular to a line with slope of 5/3
