A triangle has angles that measure 8xº,
romanna [79]

Answer:

8xº = 90º

6xº = 67.5º

2xº = 22.5º

x = 11.25°

Step-by-step explanation:

The sum of angles in a triangle is 180°

8xº + 6xº + 2xº = 180º

16xº = 180º

x = 11.25º

8xº = 11.25(8) = 90º

6xº = 67.5º

2xº = 22.5º

Hope this helps :)

Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour?
boyakko [2]
Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286

And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)
