find x, please solve this step by step.
.....answer is 24 ​

Answer 1

(3x+4)° + (3x+10)° + (5x+8)° + (50+x)° = 360° ......... (Sum of all interior angles of a quadrilateral is 360°)

3x+4 + 3x+10 + 5x+8 + 50+x = 360

12x + 72 = 360

12x = 360 - 72

12x = 288

x = 288/12

x = 24

Ans. The value of x is 24
