Answer:
<u>x = 39</u>
Step-by-step explanation:
Let's recall that the interior angles of a triangle always add up to 180 degrees.
Upon saying that, we have:
102 + 39 + x = 180
x = 180 - 102 - 39
x = 39
<u>The value of x is 39 degrees</u>
I think what ur sopposed to do is multiply all the numbers+ find out what number the letters are then multiply that with the other numbers, if that makes sence
So this one is pretty easy actually when x= a number you automatically know it'll be a vertical line cutting through the x axis. So for this problem (x=5) the line will be vertical and cut through the x axis. Hope this helps!
