Answer:
x = 6
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles
94° is an exterior angle of the triangle, then
6x + 10 + 8x = 94 ( simplify left side )
14x + 10 = 94 ( subtract 10 from both sides )
14x = 84 ( divide both sides by 14 )
x = 6
