What type of angle pair is formed by angles DCE and BCE?
1 answer:
Answer: choice 3) Complementary angles
Because angle ACD is 90 degrees (from the square marker symbol), this means that angle BCD is 90 degrees. The two angles add to 180 to form a straight line so 90+90 = 180. Now that we know angle BCD is 90 degrees, this means that breaking up this angle will have the sub-angles add back up to 90. Therefore, angle DCE adds to angle BCE to get 90 degrees. This is why the two angles are complementary.

Answer:
- x - 5y = -5; x -5y = 35
- there are no solutions, the lines are parallel so do not intersect
Step-by-step explanation:
<h3>1.</h3>We judge the x-intercept to be about 5 times as far from the origin as the y-intercept is. If we take the y-intercept of the blue line to be +1, then the equation of that line can be x -5y = -5. The y-intercept of the black line appears to be about 7 times as far from the origin as for the blue line, so the constant will be multiplied by -7: x -5y = 35.
The two equations in the system of equations could be ...
- x -5y = -5
- x -5y = 35

<h3>2.</h3>We have assumed the two lines are parallel, so they will not intersect. A point of intersection would be a solution to the system. The system of equations will have no solutions.
