Answer:
x = 23
Explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
92° is an exterior angle of the triangle, then
2x + 46 = 92 ( subtract 46 from both sides )
2x = 46 ( divide both sides by 2 )
X=18
you can find what the missing angle is by subtracting 92 from 180 since its a straight line. After putting in the missing angle you can easily solve for 2X which is 36 and then divide by 2 and get 18.
