Answer:
<h2>The value of x is 8.</h2>
Step-by-step explanation:
We know that 
Each angle is defined as
and 
Replacing all in the first equation, we have
Therefore, the value of x is 8.
Answer:
<h2>Increase.</h2>
Step-by-step explanation:
Two-dimensional space is modelled by the coordiante system with 4 quadrants only, and the axis are x and y, the independent and the dependent variables, respectively.
On the other hand, the three-dimensional space has three coordinates, x, y and z. The extra coordinate allows to have a three-dimensional space. Also, this extra coordinate increases the number of quadrants, actually, they are called octants, becayse they are eight.
Therefore, the word missing here is "increase".
Answer:
2 hours = 1,100
6 hours = 3,300
Step-by-step explanation:
divide 1,650 by 3 hours and get 550 as the average miles traveled per hour
times 550 by the hours desired and get you answer
hope this helps!!
