Answer:
Cosine Rule (The Law of Cosine)
The Cosine Rule states that the square of the length of any side of a triangle equals the sum of the squares of the length of the other sides minus twice their product multiplied by the cosine of their included angle.
a² = b² + c² - 2bc Cos A
where,
a,b,c are sides of a triangle
A is the included angle
Answer:
The answer is A ur welcome
Step-by-step explanation:
Answer: Width = 9 inches
Length = 12 inches
Step-by-step explanation: A = (w+3)(w)
A = w2 + 3w = 108
w2 + 3y - 108 = 0
This is the factor of the problem: (w - 9) (w + 12) = 0
This equals to w + 12 = 0
w = -12
Then the final answer would be Width = 9 inches
Length = 12 inches.
Hope this helps!

Answer:
34.72 feets
Step-by-step explanation:
Using the relation :
Length of tree / shadow of tree = height of melody / shadow of melody
From the details given in the question :
Let height of tree = h
h / 62 = 5.6 / 10
Cross multiply
h * 10 = 62 * 5.6
h = 347.2 / 10
h = 34.72 feets
Hence, the height of tree is 34.72 feets
2.248 rounded to the whole number would be 2, because if we look after the number 2, the 2nd 2 it is less than 5. Therefore we round backwards, and the answer is 2.
So, 2.248 rounded to the nearest whole number would be 2.
Hope I helped ya!! xD
