3) Given that lines a and b are parallel, and lines o and t are parallel, find the point value of x.
S

o
7x+50
5x + 11
t
Ox3
O x = 13.6
O x = 26

X = 3°

Step-by-step explanation:

Since O and T are parallel you can use alternating lines

7x + 5° = 5x + 11° (alt. angles, O||T)

Move the 5x and the 5°

7x - 5x = 11° - 5°

2x = 6°

Divide both sides by 2

x = 3°

This is assuming 11 is an angle
