here is ur answer..
x+115°=180° (linera pair)
x=180°-115°
x=65°
now ..the sum of 3 sides of the triangle is 180°
therefore
65°+31°+y=180°
91°+y=180°
y=180°-91°
y=89°
therefore ×=65° & y=89°
x+115°=180° (linera pair)
x=180°-115°
x=65°
now ..the sum of 3 sides of the triangle is 180°
therefore
65°+31°+y=180°
91°+y=180°
y=180°-91°
y=89°
therefore ×=65° & y=89°
