What are soulutions to x^2 - 2x - 24 = 0<br> who is brainliest
ratelena [41]

Which angles is supplementary to angle 7
xenn [34]

Answer:

Angle 8

Step-by-step explanation:

Angles 7 and 8 are supplementary because they are both on a straight line.
A straight line is 180*, and the line that forms the angles 7 and 8 splits 180* into those degrees in the angles, so both of those angles add to 180* which makes them supplementary.
