I think it's the second answer
Hope this helps :)
Supplementary angles add up to 180º
If one is 40º, then the other is (180º-40º) = 140º
None of those choices describes a plane.
choice C is the only example of a plane.
The answers in order are
Y= 10/4
Y=5/3
Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points.
