Let x and y be the two unknown angles.
They are supplementary, so they add to 180 degrees
Solve for y to get (subtract x from both sides)
------------------------------------------------
"one is 10 more than twice the other" means that
Plug in and solve for x
Notice how y is replaced with 180-x
This is approximate
------------------------------------------------
Now plug into to find y
This is approximate
------------------------------------------------
We found that and approximately
So the two angle measures are approximately 56.67 degrees and 123.33 degrees
