Question

find the value of X Y and Z in the following figure​

Answer 1

Answer:

angel Y is 110.

angle X is150.

angle Z is 40.

Answer 2

Answer:

we know that sum of angles in triangle is 180°

⇒40°+30°+y=180°

⇒y=110°

and now z,y on straight line i.e., z+y=180°

⇒z+110=180°  

⇒z=70°

and  we know that exterior angle = sum of opposite interior angles

⇒40°+y=x

⇒40°+110°=x

x=150°

similarly z=40°+30°   (exterior angle)

z=70°

∴ x=150° ; y=110° ; z=70°
