Answer:
x=84
Step-by-step explanation:
We know that the angles in a triangle are equal to 180.
39+57+x=180
96+x=180
x=84
Answer:
The lines are perpendicular
Step-by-step explanation:
we have

isolate the variable y
----> equation A
The slope of the line A is 
-----> equation B
The slope of the line B is 
Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In this problem
The slopes of line A and line B are opposite reciprocal
therefore
The lines are perpendicular
Answer:
78.125
Step-by-step explanation:
If 312.50 is 100% then 25% is 78.125
