Answer:
Step-by-step explanation:
Formula
c^2 = a^2 + b^2
Givens
Hypotenuse (c) = 45
a = 40
b = ?
Solution
45^2 = 40^2 + b^2
2025 = 1600 + b^2 Subtract 1600 from both sides.
2025-1600 = 1600-1600 + b^2 Combine
425 = b^2 Take the square root of both sides.
√425 = √b^2
b = 20.62
Answer
The third side is 20.62 cm
Combine like terms so add 4b and 15b together and add 7 and 3 together and then the answer would be 19b-10
Answer:
Step-by-step explanation:
Aromatic amine is generally less nucleophilic than aliphatic amine because of the aromatic delocalisation of the lone pair. Ketones are also less reactive compared to aldehyde and Reaction between aromatic amine and aromatic ketone is possible leading to the formation of Schiff's base in aqeous ethanoic solution.
