1c

2d

x=2

8°

Step-by-step explanation:

Here's your solution

=> we know that the sum of all angles formed on a straight line is equal to 180°

=> EC is a straight line

=> 1st angle = (6x + 2)

=> 2nd angle = (8x + 6)

=> 3rd angle = (7x + 4)

=> now, (6x + 2) + ( 8x + 6) + (7x + 4) = 180°

=> 6x + 2 + 8x + 6 + 7x + 4 = 180°

=> 21x + 12 = 180°

=> 21x = 180°- 12°

=> 21x = 168°

=> x = 168°/21

=> x = 8°

hope it helps
