A system of linear equations is a set of two linear equations with two variables.
For this case what we must do is take into account that the angle can be measured in two ways starting from the positive x axis.
- <em>1) Counterclockwise
</em>
- <em>2) Clockwise direction
</em>
We have then that the measures between both lines are given by:
1) Counter-clockwise: 90 degrees
2) Clockwise: -90-90-90 = -270 degrees
Answer
two possible measures of the angle below are:
-270 ° and 90 °
Answer:
29
Step-by-step explanation:
c² = 2² + 5²
c² = 4 + 25
c² = 29
c = sqrt(29)
Answer:
if donuts are 2 for each and cookies for 1 each it could be
X x 2 and X x 1
one equation could be 4 donuts for 2$ and 7 cookies for 1$
