the measure of angle xyz is 140degree what is the value of x (2x+6)degree

no, she is showing u in which the context the x is coming from.

Your question makes no sense. Is xyz> = 2x+6 ?

To find the value of x, you need to solve the equation:

2x + 6 = 140

First, subtract 6 from both sides of the equation:

2x = 140 - 6
2x = 134

Next, divide both sides by 2:

x = 134 ÷ 2
x = 67

Therefore, the value of x is 67.
