Answer 1

x=30° it's is angle of right triangle

Answer 2

Construction : Extending EF and AB,

Angle CEF + Angle CEG = 180° [Linear Pair]

130° + Angle CEG = 180°

Angle CEG = 50 °

AH // GF and BC Is the transversal

Angle ABG = Angle BGE = 85 °[ Alternate interior angles]

Angle CGE + Angle BGE = 180° [Linear Pair ]

Angle CGE = 180 ° - 85°

Angle CGE = 95°

IN triangle CGE,

Angle CGE + Angle CEG + x = 180° [ Angle Sum property]

95° + 50° + x = 180°

x = 180° - 145°

$<h3>x = 35 °$
