Question

Please help me! i’m a bit confused. i’m not the best with math.

Answer 1

30 + 4x + 2 + 180 - (8 + 6x) = 180;The sum of all angles in a triangle is 180

32 + 4x - 8 - 6x = 0

2x = 24

x = 12

Bolded part, explanation: On a straight line, the sum of all angles is 180 degrees. We have the value of outside the triangle, the exterior angle, which, when is added with interior angle, gives 180 degrees. So we substract 8 + 6x from 180, that's the third angle in a triangle.
