Question

Find the value of 'x' in the following figure ​

Answer 1

Answer:

ADB= 30 degrees

x = 150 degrees ....

use the angle sum property of triangle as adb is 120 degrees

Answer 2

Answer:

Step-by-step explanation:

∠BEF = 180 - 120 = 160°

∠ADE  + ∠BEF  + ∠DAE = 180

∠ADE = 180 - ∠BEF - ∠DAE  = 180 - 60 - 30 = 90°

∠CDF = 180 - ∠ADE = 180 - 90 = 90°

∠DCF = 180 - ∠DFC - ∠CFD = 180 - 60 - 90 = 30°

∠X + ∠DCF = 180°

=> ∠X = 180 - 30 = 150°
