Answer:
Step-by-step explanation:
EI = IG . . . . . . . . . . . .diagonals of a rectangle bisect each other
2x +7 = 6x -13 . . . . . substitute given expressions
20 = 4x . . . . . . . . . . add 13-2x
5 = x . . . . . . . . . .. . . divide by 4
EI = 2x+7 = 2·5 +7 = 17
FH = 2·EI = 2·17
FH = 34
__
∠IGF = ∠IFG = ∠IEH = ∠IHE = 59° . . . . mirror symmetric angles are congruent
∠EIH = 180° -∠IEH -∠IHE = 180° -2(59°)
∠EIH = 62°
