Question

find x in following figures​

Answer 1

Step-by-step explanation:

Given: ‹A = 56°

‹ACD= 123°

Required: ‹x= ?

solution: ‹ACD + ‹ACB = 180°

123° + ‹ACB = 180°

‹ACB = 180°- 123°

‹ACB = 57°

‹ACB + ‹ABC + ‹BAC = 180°

57° + x° + 56° = 180°

x° + 57° + 56° = 180°

x° + 113° = 180°

x° = 180°- 113°

x° = 67°
