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

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:

When a transversal cuts two parallel lines, the corresponding angles are equal

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

Step-by-step explanation:

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

In a plane, two lines which are parallel exist in the same axis.

In essence, any line which is perpendicular to one of two parallel lines is also perpendicular to the other.

This concept is evident in the model of ladders, where each of the vertical lines are perpendicular to the parallel step lines(horizontal lines).

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
