Answer 1

Explanation:

The angle at W plus the 144 degree angle form a 180° ( straight line)

so that angle is 36°

the three angles inside the triangle = 180 °

36° + 6x+1 + 7x = 180 °

13x = 143

x = 11°

Answer 2

x = 11.

Explanation:

The sum of the 2 base angles = 144 (external angle of a triangle theorem)

So,

6x + 1 + 7x = 144

13x = 143

x = 143/13 = 11,
