Omar used this equation to find the value of x when m || n, but he is checking his work. Determine if Omar's equation will work. If not, find his error and correct it.

Omar's errour was when he thought that consecutive exteriour angles were congruent, when they REALLY form a linear pair, therefore you sum them up to 180°:
[tex]\displaystyle 180° = 59° + [10x - 1]° → 180° = [58 + 10x]° → 122 = 10x; 12\frac{1}{5} = x[/tex]
I am joyous to assist you at any time.
