Do you mean how you can get 16 in a multiplication problem? Then the answer would be 2 times 8 which would equal 16. Hope this helped.
the 2 angles are congruent so...
x+40=3x set the 2 equations equal to each other
40=2x subtract x from both sides
20=x divide by 2
x=20 is the final answer
Have a blessed day!
