Triangles(9) Using the giveninformation in thefigure find La, LbmarksS

1.	Triangles(9) Using the giveninformation in thefigure find La, LbmarksS100
Answer» In given fig. Angle c + 100 = 180 (linear pair)Angle c = 80 Angle b = 70 (Vertical opposite) By sum property of triangleAngle a + Angle b + Angle c = 180Angle a + 70 + 80 = 180Angle a = 180 - 150 = 30 Hence, Angle a = 30, Angle b = 70, Angle c = 80

Triangles(9) Using the giveninformation in thefigure find La, LbmarksS100

Answer»

In given fig.

Angle c + 100 = 180 (linear pair)Angle c = 80

Angle b = 70 (Vertical opposite)

By sum property of triangleAngle a + Angle b + Angle c = 180Angle a + 70 + 80 = 180Angle a = 180 - 150 = 30

Hence, Angle a = 30, Angle b = 70, Angle c = 80
