Answer:
x = 5
Step-by-step explanation:
The equation of a vertical line is of the form ...
x = constant
In order to make that line go through a point that has an x-coordinate of 5, the value of the constant must be 5.
x = 5

Step-by-step explanation:
The angles are B and C.
The three angles add up to 180º
A=80º
B
C
A+B+C=180º
80º+B+C=180º
B+C=180º-80º
B+C=100º (1)
The ratio between A and B is 7/13 ; therefore:
B/C=7/13 ⇒B=7C/13 (2)
With the equations (1) and (2), we make a system of equations:
B+C=100
B=7C/13
We can solve this system of equations by substitution method:
7C/13 + C=100
least common multiple=13
7C+13C=1300
20C=1300
C=1300/20
C=65
B=7C/13
B=7*65/13
B=455/13
B=35º
Answer: The measures of those two angles are 65º and 35º.
