Answer 2

Answer:

given = angle ABD = 60°

angle BCA = 50°

angle DBC = 30 °

To Find = x° ,y° and z°

Find = ∆ABC = 180°

= Angle ABC +Angle BCA + Angle BAC = 180°

=angle(60°+ 30°) + angle 50° +x°= 180°

=90° + 50° + x° = 180°

= 140°+x° =180°

= x° = 180°-140°=40°

now ∆ ABD = 180°

= angle ABD + angle BAD + angle ADB = 180°

= 60° + 40°+y° = 180°

= 100° +y° = 180°

y° = 180°- 100°= 80°

and ∆ BAC = 180°

= 30° + 50° + z° = 180°

= 80° + z° = 180°

= z° = 180° - 80° = 100°

so,

x° = 40° , y° = 80° and z° = 100°
