In a plane if a line is perpendicular to one of two __ lines then it is also perpendicular to the other.
a. perpendicular
b. parallel
c. skew
d. intersecting

B. In a plane if a line is perpendicular to one of two parallel lines then it is also perpendicular to the other.

Step-by-step explanation:

We have been an incomplete statement. We are supposed to fill in the blank for our given statement.

Statement: In a plane if a line is perpendicular to one of two __ lines then it is also perpendicular to the other.

We know that when a transversal cuts two parallel lines, then corresponding angles are equal.

We know that parallel lines never intersect each other. When a third line is perpendicular to one of parallel lines, then the third line must be perpendicular to other line as well.

Therefore, the correct term to fill in the given blank is parallel and option B is the correct choice.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
