AB II CD and GE is transversal. .. LAGE = LGED [Alternate angles] => AGE = 126°. Fwther, LGED = LGEF + LFED => 126° = LGEF + 90° [•: EF l. CD] => LGEF = 126° - 90° = 36°. Again, AB II CD and GE is transversal. • LFGE + LGED = 180° [Sum of interior angles on the same side of transversal is 180°.] => LFGE + 126° = 180° :::::) LFGE = 180° - 126° = 54°.
