Question

Find the X. Answer iscoming 45° tell me how it came...​

Answer 1

Step-by-step explanation:

angle ABC = angle ABD - 180 ( linear pair of angle )

angle ABC = 120° - 180°

= 60°

WE KNOW THAT , SUM OF ALL ANGLES OF TRAINGLE IS 180°

X + X + 30° + 60° = 180°

2x = 180° - 90°

x = 90/2

x = 45°

Answer 2

Step-by-step explanation:

Note : sum of all interior angles of triangle = 180⁰

X = 45⁰

X + 30 = 75⁰
