Find the sum of a, b, c, d, e, f, g and h. Share with your friends Share 1 Brijendra Pal answered this Hi, Using sum of quadrilateral angle property, angle GDC+angle DCJ+angle CJG+angle JGD = 360 also using vertical angle property, angle GDC= angle EDF, angle DCJ=angle ACBangle CJG=angle KJLangle JGD=angle HGI........1So putting all these, angle EDF+angle ACB+angle KJL+angle HGI= 360 ....2also in triangle ABC, using angle sum property, angle ACB+h+g= 180 ....3similalry in triangle DEFangle EDF+f+e= 180 ....4similalry in triangle GHI angle HGI+c+d= 180 .....5similalry in triangle JKL angle KJL+a+b= 180 .....6Adding equation 3,4,5,6 angle EDF+angle ACB+angle KJL+angle HGI+a+b+c+d+e+f+g+h= 720From equation 2 360+a+b+c+d+e+f+g+h= 720a+b+c+d+e+f+g+h= 360 2 View Full Answer
