Question

in figure find the value of x​

Answer 1

Answer:

Step-by-step explanation:

Given :AB║CD

angle:∠AGE = ∠HGB                 ( vertically opposite ∠s )

so, ∠HGB = 110°

∠HGB + ∠GHD = 180°    (sum of interior angles )

so, 110° + (3x - 20)° = 180

110° + 3x - 20 = 180

90° + 3x = 180

3x = 180° - 90°

3x = 90°

x = 90/3

∴x = 30°

so angle = 3 ×30 - 20

              =90 - 20

             =70°

so,∠GHD = 70°
