Question

5. In the adjacent figure, BC || DE. Find:
(i) Angle ABC
(ii) Angle ADE​

Answer 1

Given:-

angle a = 40°

angle ecb= 95°

To Find:-

(i) Angle ABC

(ii) Angle ADE

Solution:-

$\angle \: c = 180 - 95(linear \: pair) \\\angle \: c = 85 \\ ⇒\angle \: abc = 180 - (40 + 85) (angle\: sum\: property)\\ ⇒\angle \: abc =55 \\ ⇒\angle \: ade =55(corresponding \: angles)$

hope this helps.!
