If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.
b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°
Answer:
now using the formula (a-b) (a2+ab+b2)=a3-b3
=>x3-63
x3-216#answer
Answer:
What are the answer choices? I would help but you didn't attach or write them.
Step-by-step explanation:
I'm fairly sure it is 0 because it is impossible to roll a number greater than 13 with a 12 sided die.
-4(n+1)-(n+2)
(-4n-4) - (n-2)
-3n-2
