Ef is parallel to hg
how to find y ?

Since angle H is 110 degrees, arc EFG is 220 degrees because the measure of an inscribed angle is half of the measure of its intercepted arc. Now that we know the measure of arc EFG, the measure of arc EHG is 140 degrees. Based on the rule that was mentioned before, if the measure of arc EHG is 140 degrees, the measure of angle y is half of 140 which is 70 degrees. :)

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
