The missing measure of angle x is determined as 129 degrees.
What is the missing measure?The sum of all angles formed on the same side of straight line is 180 degrees.
Let AB be the line in the figure and CD be another line that cuts the line AB at O.
now from figure let given angle be
∠AOC = 51°
and ∠BOC = x°
Now since we know that the sum of all angles formed on the same side of straight line is 180 degrees.
Therefore, on line AB,
∠AOC + ∠BOC = 180°
Putting the values of ∠AOC and ∠BOC we get,
51° + x° = 180°
Subtracting 51° both the sides we get,
x° = 180° - 51°
x° = 129°
which is the required value of angle x.
Hence, the missing measure is x = 129 degrees.

If we went back in time before modern channel engineering, what would have been true about the nile in this region?
Before modern channel engineering, the Nile River would have been largely uncontrolled and unpredictable in its flow patterns.
What were the condition of the Nile river before modern channel engineeringIn ancient times, the people living along the Nile developed various methods to manage the river's flooding, such as building levees and canals to divert water to irrigate fields. However, these methods were limited in their effectiveness and could not prevent all damage caused by the river's unpredictable flows.
Without modern channel engineering, the Nile would have likely continued to fluctuate greatly in its flow patterns and cause periodic flooding, which could have both positive and negative impacts on the surrounding ecosystems and human settlements.
The lack of modern engineering techniques would have limited the ability of humans to manage the river's flow and mitigate the effects of flooding, drought, and other natural disasters.
