Sum of all exterior angles = 360°.
Number of sides = 360 ÷ 40 = 9
Each interior angle = 180 - 40 = 140°.
Answer: <span>The regular polygon has 9 sides and each of its interior angles 140°</span>
37. 3/8 hours
You can get this by dividing 3/4 by 2.
The key to doing these types of problems is remembering that if they are going faster by that much, it doesn't matter what the speeds are. You can treat it as if one is standing still and the other is going 2mph.
The answer would be C. 600 because 600x0.20= 120
Answer:
∠ ACB = 21°
Step-by-step explanation:
the inscribed angle ACB is half the central angle AOB , subtended by the same arc AB , then
∠ ACB = 
∠ AOB = × 42° = 21°
Answer:
6
Step-by-step explanation:
-6×(-1)=6
When multiplying two negative numbers, the product will always be positive. When multiplying one negative number and one positive number, the product will always be negative.
So think of this equation as 6×1, since two negatives equal a positive.
