Question

find X and Y in each of the following

Answer 1

X=80(exterior angle property)  Similarly y=100

Answer 2

hey mate! here's your answer!

since, in triangle BCD,

x is an exterior angle.

so, 50° + 30° = x

=> 80° = x ....Ans

now, in ∆ABE ( E is the angle which is supposed on the point where angle y is formed)

since, y is here an exterior angle.

=> 20° + x = y

=> 20° + 80° = y

=> 100° = y ....Ans

hope you understood!
