Question

AB//CD . FIND X. pls tell fast ​

Answer 1

Answer:

Firstly join A and C

line AC bisect angle ECD and angle EAB

Now in triangle ECA

angle ECA = 116/2 =58°

angle EAC = 104/2 = 52°

Let angle AEC = X

angle EAC + angle AEC + angle ECA = 180°

( sum of all angle property in triangle)

52° + X + 58°= 180°

X + 110° = 180°

X = 180° - 110°

X = 70°

Answer 2

Answer:

x = 140⁰

Step-by-step explanation:

draw a line passing through e and parallel to ad and cb

now,

180⁰ - 104⁰ = 76⁰

180⁰ - 116⁰ = 64⁰

now add them...76⁰ + 64⁰ = 140⁰
