Answer: 84.8°
Step-by-step explanation:
a²+b²+c²-2bc(cosA)
cosA = b² + c² - a² / 2bc
That is the formula we will be using.
Then, plug in our numbers.
cosP= 500² + 380² - 600² / 2(500)(380)
cosP= 34400/380000
cosP≈ 0.09052631
cos⁻¹(0.09052631) ≈ 84.81
∠P = 84.8°
Answer:
(3, - 1 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin then multiply each coordinate by
(6, - 2 ) → (6 × , - 2 × ) → (3, - 1 )
Answer:
exact volume= 12320ft³
approximate volume= 12308.8ft³
Step-by-step explanation:
exact volume= 22/7×14² x 20
approximate volume = 3.14x14²x20
