Answer:
(4.2x100).(5.7x100) = 239.400
Step-by-step explanation:
We need to determine the product of (4.2x100).(5.7x100).
We know that when two numbers are multiplied together, the product is the same regardless of the order of the multiplicands. For that reason, we can multiply all together, and the result will be the same regardless of the order of the multiplicands:
Then:
(4.2x100).(5.7x100) = 4.2x100x5.7x100 = 420x570= 239.400

Answer:
∠B = 41°
Step-by-step explanation:
∠BCD is an exterior angle of the triangle

72 + ∠B = 113 ( subtract 72 from both sides )
∠B = 41°
