If gp=ph, ga =17, med = 37, and mab = 87, find each measure.

We know that
mAB = 87°
mED = 37°
mEFA=mBCD
360°=mAB+mED+mEFA+mBCD
360=87+37+2mBCD> mBCD=[360-87-37]/2> mBCD=118°

therefore
m BCD=118°
m FA=m EFA/2> m FA=118/2> 59°
m FA=59°
m DC=m BCD/2> m DC=118/2> 59°
m DC=59°

HB=GA> HB=17
DB=2*HB> DB=2*17> DB=34

EG=GA> EG=17

the answers are
DB=34
EG=17
mBCD=118°
mFA=59°
mDC=59°
