Question

A truss bridge is shown with two parallel horizontal beams crossed by vertical and slanted beams.

Find the value x, the degree of slant for the beam.


The value of x is ___​

Answer 1

40 degrees

Explanation:

Because the horizontal beams are parallel, we can identify "x" and the marked 40 degree angle as opposite interior angles (angles on opposite sides of a traversal that crosses parallel lines that are also inside the parallel lines) and we know they are equivalent by definition.

Answer 2

40 degrees

Explanation:

Because the horizontal beams are parallel, we can identify "x" and the marked 40 degree angle as opposite interior angles (angles on opposite sides of a traversal that crosses parallel lines that are also inside the parallel lines) and we know they are equivalent by definition.
