Question

D
12. In the adjoining figure, AE|| BC With the help of the given information find the
Value of x and y
A
(x + 19)
[Hint: ZDAE = ABC = x + 19 = y - 11 => x-y=-- 30
E
...)
(2x + y)
2x+y +y - 11 *x + 11 = 180 = 3x + 2y = 180...(1). Solve (1) and ())

Answer 1

Answer:

DCE=∠EAB (Alternate angles as AB∣∣DE and AE is transversal)

∠DEC=35

∘

In △DCE, we have

∠DCE+∠CED+∠CED=180

∘

(Angle sum property)

∠DCE+35

∘

+53

∘

=180
