let point A has coordinates (-9;12),B(-3;12),C(-5;10) and D(-11;10).Then the vector AB={6;0}, BC={2;-2}, CD={6;0}, AD={2;-2} and their and the length of the vectors


These angles are adjacent which means they share a side and a vertex. Adjacent angles are also supplementary so the measure of the two angles add up to 180 degrees. Since angle 1 is 137 degrees, angle two is 43 degrees. I hope this explanation helps you.
Answer: $16.06 (rounded to nearest cent)
Step-by-step explanation:
Total parts in which a spinner is divided = 4
Each part is named as 1,2,3,4.→Total possible outcome when spinner gets in the motion.
When we toss a coin , total possible outcome = {H,T}
So, all the possible outcome when Rihana spins the spinner and tosses a coin = {H 1 , H 2, H 3 , H 4, T 1, T 2, T 3, T 4}=8
