hmmm, the slope is undefined, that means, is a vertical line then, check the picture below.
Answer:
the answer is C. 100°
Step-by-step explanation:
The known angle is supplementary with angle A (Look at the attachment), that means that the sum of the known angle and A is 180°, therefore the value of angle A is 80°
then A and B are corresponding angles, which means that they have the same value, that happens because <em>p</em> and <em>q</em> are parallels and both cut line <em>n</em> in the same way. the value of the angles B is 80° too.
Angles B and C are corresponding too, so the value of the angle C is 80°.
Finally angles C and X are supplementary too for which the sum of X and C (80°) is 180°, <em>so the value of X is 100°</em>

Answer:
1/√2
Approximate numerical value
1/√2 = 0.707106781186548
---------------------------
Rationalize the denominator
(1/√2) * (√2 / √2) = √2 / 2
