Question

In the figure angle,ABC and angle BDE are exterior angle of∆ BCD .If angle ABC = 110°, angle BDE = 130° then find the value of x,y and z​

Answer 1

Answer:

angle y = 70 degree

angle z = 50 degree

angle c = 70 + 50 + c = 180 degree

angle c = 60 degree

Answer 2

Answer:

Step-by-step explanation:

y+110°=180°(linear angle)

y=70°

z+130°=180°(linear angle)

z=50°

x+y+z=180°(sum of angles in a triangle)

x+70°+50°=180°

x+120°=180°

x=60°

So the values of x=60°,y=70°,z=50°
