Question

form adjacent fig find m angle ABD ​

Answer 1

Answer:

x +x∘

+50∘

=180∘

(Straight angle made on AB at point B)

2x+50∘

=180∘

2x=180∘

−50∘

=130∘

x=

2

130∘

=65∘

y∘

+y∘

+70∘

=180∘

(Straight angle made on AC at point C)

2y+70∘

=180∘

2y=180∘

−70∘

=110∘

y= 2

110∘

=55∘

In △BOC

x+y+z=180∘

(Angle sum property)

65∘

+55∘

+z=180∘

z=180∘

−120∘

=60∘
