directly oppositre angles around circle sum to 180 degrees
angles on straight line sum to 180
so you have the two interior triangle angles
therefore have third as sum to 180
then i think its corresponding angles to find the other angle around x
then just do 360 minus those two numbers
180 - 137 = 43
bc angles on a straight line add up to 180 degrees
so thats the angle on the right inside the triangle
vertically opposite angles are equal so the angle to the left of that is 65 degrees
to work out the top angle we can do: 180 - 65 - 43 = 72
180 - 65 = 115, because angles on a straight line add up to 180 degrees
co-interior angles add up to 180 degrees
so we can do 180 - 115 to get 65 degrees
so x is 360 - 72 - 65
which is 223 degrees
