Answer:
x = 4
Explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.
We can write the following equation to find the value of x based on this information:
6x + 6 + 17x + 2 = 100
23x + 8 = 100
- Subtract 8 from both sides
23x = 92
x = 4
