Nnesha (nnesha):

220 ???

Nnesha (nnesha):

can anyone explain to me please

OpenStudy (mokeira):

angles at a point add up to 360

OpenStudy (dumbcow):

i might be looking at the wrong arc segment GEH would mean that you start at point G, then arc goes through point E and stops at point H so in that case the arc is 360-30 = 330

OpenStudy (mokeira):

i thought it was GEF sorry

OpenStudy (mokeira):

360-30

Nnesha (nnesha):

why we just subtract 30 ?/ not understand

OpenStudy (mokeira):

|dw:1407304838369:dw| you are finding the angle measurement for where I have traced around so all you do is remove that unwanted part which is 30 degrees
