Correct?

OpenStudy (jackthegreatest):

DHG = 130 HG = 40 GF = 140

OpenStudy (jackthegreatest):

If the line HF is the diameter as well

OpenStudy (jackthegreatest):

actually nvm, HG and EF are equal in angle

OpenStudy (jackthegreatest):

so since they both 40, 180-40=140

OpenStudy (jackthegreatest):

you are correct

OpenStudy (welshfella):

I never did arc measurements in school or college so I'm confused about this one. If m<DPH = 90 degrees shouldn't th arc DH be = 90?

OpenStudy (welshfella):

Excuse my ignorance!!!

OpenStudy (welshfella):

OH OK - I see it now!!! lol
