Answer:
x = 61
Step-by-step explanation:
First you must set up an equation to find the x value. Since we know its supplementary we know all the angles added together are going to equal 180.
180 = 2x + 3 + x - 6
Then just solve for X.
180 = 2x + 3 + x - 6
180 = 3x - 3 Combine like terms
+3 +3 isolate x
183 = 3x
/3 /3
61 = x
