CIRCLES C8

In the figure below, find the value of <FGE.



Solution

<FEG = <HFG

<FEG = 540 [angles in alternate segments are equal.]

Consider GEF

<EFG + <FGE+ <GEF = 1800 [total degrees of a triangle]

 (390 + 540) + <FGE + 54= 1800

930 + <FGE + 540 = 1800

1470 + <FGE= 1800

<FGE= 1800 - 1470

<FGE= 330  


<FGE = 330
