Answer» the sum of number 40 be x Angel EFGH is a parallelogram.⇒ ∠FGH+FGK=180 o [ Linear pair ]⇒ ∠FGH+70 o =180 0 ∴ ∠FGH=110 o ⇒ ∠FGH=∠FEH=110 o [ Opposite angles of a parallelogram are equal ]∴ x=110 o ⇒ ∠EHG+∠FGH=180 o [ Sum of adjacent angles of parallelogram is 180 o . ]⇒ ∠EHF+∠FHG+∠FGH=180 o ⇒ 40 o +z+110 o =180 o ⇒ z+150 o =180 o ∴ z=30 o ⇒ ∠EHG=40 o +z=40 o +30 o =70 o ⇒ ∠FHG+∠HGF+∠GFH=180 o [ Sum of angles of triangle is 180 o ]⇒ 30 o +110 o +y=180 o ⇒ 140 o +y=180 o ∴ y=40 o We get, x=110 o ,y=40 o ,z=30 o |
