Answer:
x = 100°
Explanation:
The polygon has 6 sides, meaning it's a hexagon. In the picture you can see the following steps under #1:
(6-2) x 180° = 4 x 180 = 720°
720 is the total amount that all the angles should add up to, including the missing number x.
To solve for x add all of the angles up:
120 + 156 + 145 + (x + 9) + x + 90 = 720
520 + 2x = 720 (subtract 520 from both sides)
-520
2x = 200 (divide 200 by 2 to have x on its own)
x = 100°
To make sure it's correct, plug in the value (100°) for x in the original equation to check the answer:
120 + 156 + 145 + 100 + 9 + 100 + 90 = 720
720 = 720 Correct
The greatest number of treats you can buy is 7 because you bought $18 worth of dog food, leaving $7 for treats.
Average speed for the entire journey was 62 miles per hour.
Total time of the journey was 5 hours.
In first 2 hours, her average speed was 60 miles per hour. This means, she covered 120 miles in first two hours, as
Distance = Speed x Time
The total distance of the entire journey was:
Total Distance = 62 x 5 =310 miles
Out of these 310 miles, she covered 120 miles in first two hours. So this means she covered (310 - 120) miles in next 3 hours.
Thus she covered 190 miles in 3 hours. So her average speed will be 190/3 miles per hour which is equal to 63.33 miles per hour.
So, the average speed for last 3 hours of the trip was 63.33 miles per hour
Your answer would be 12 because the green is half of the red in which it is now 2, 5, and 1.5 we multiply these numbers together and get the volume in which the answer is 12 (: hope I could help, if you could make me brainalist that would amazing!
