Question

in the given figure ,BD=BC and <DBC=40°, find x ,y and z​

Answer 1

Answer:

y=70( sides opposite to equal angles are always equal)

z=70( sum of three sides in a triangle is equal to 180)

180-40= X

X=140

Answer 2

Step-by-step explanation:

x = 140° because it's on a straight line and (180-40)°

y = z because it is an isosceles triangle

And y = 70° ( since y = z )

therefore z = 70°
