Answer:

33

Step-by-step explanation:

The bottom angle is a completely straight line, and that means the angle is 180 degrees.

180 - 81 = 99

So, this means 3x = 99. We need to isolate the variable, so we have to divide everything by 3.

x = 33

Answer:

waaait i know how to do this lol ( i feel like this is correct)

x = 33

Step-by-step explanation:

so a line is 180 right?

so make the equation like this

180 = 81 + 3x

now solve for x by doing algebra

(minus both sides by 81)

3x = 99

x = 33
