Answer 2

The  value of angle 'a' from the figure is $40\textdegree$and option(ii) is correct.

Step-by-step explanation:

Given:

Two gates consist of vertical posts, horizontal struts and diagonal

beams.

As per figure the angle between  vertical struts and diagonal  is given is $40\textdegree$.

To Find:

The angle 'a' from the figure.

Concept Use:

When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. Alternate interior angles angles are always equal.

Solution:

As given,Two gates consist of vertical posts, horizontal struts and diagonal.

As per figure the angle between  vertical struts and diagonal  is given  $40\textdegree$.

The  given angle between  vertical struts and diagonal  and angle a which is to be find out are  alternate interior angles.

Since Alternate interior angles angles are always equal.

Thus,the value of angle a is $40\textdegree$ and option(ii) is correct.
