1. This is a nonagon. A nonagon is a 9-sided polygon; the figure has 9 sides.
2. This is not a regular polygon. A regular polygon is equiangular and equilateral which means that all of the angles are equal in measure and all of the sides are equal in length. The figure shown does not have equal sides or angles; therefore, it is an irregular polygon.
(-9,8) is the answer (h,k) is the equation
Answer:
5 in^2
Step-by-step explanation:
Area of square: 2*2=4
Area of triangle: 2*1/2=1
4+1=5
1 19/100 is your answer........
Two supplemental angles add up to 180°
So we have (A + B = 180°)
The measure of one of them is always 180° - the other.
A = 180° - B
B = 180° - A
