Answer:

x = 40 degrees

Step-by-step explanation:

By corresponding angles, the angle above the 75 degree angle is also 75 degrees. Since angles of a triangle add to 180 degrees, x=180-75-65 = 40 degrees.

Answer:

[tex]x=40^\circ[/tex]

Step-by-step explanation:

Since the two bases are parallel to each other, by the Corresponding Angles Theorem, the left angle of the upper triangle must also be 75°.

And since the interior angles of a triangle always equal 180:

[tex]75+65+x=180\Rightarrow x=40^\circ[/tex]
