okay so we know the angles in a point add up to 360° so first of all we know we have a right angle as you can see so we're going to subtract 90° off of the 360° is 270° take away 20° as we can also see that we don't need to do any working out together so if we take away 20° from 270° it will give us 250° now we need to work out the x and the y so we know that in total there is 12 x's as seven add five is 12 now we know that there is two y's in total as there is a two on the bottom and no other y's so now we know they will have 12 x's and two y's we can see that y is 11 as two y is 22 and if Y is 11 we could subtract 22 from 250 to get 228 and then if we divided by 228 by 12 it will give us 19 so X is 19 and if you add 95° 133° 90° 20° and 22° it will give you 360°
