Help me with this please

Step-by-step explanation:

so use the similar idea , first find  'y'   by using that all the way around the circle is 360 , soo

360 = 110 + y + 80 + 90

80 = y

now that we know that, notice that the side with a 4 also has 80, so we now know that x = 4  :)  b/c of similarity

x = 4

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
