Answer:
Option 3. 360°
Step-by-step explanation:
we know that
The sum of the measures of the interior angles of triangle is equal to 180 degrees
The figure has two triangles
therefore
[tex]2(180\°)=360\°[/tex]
Alternative Method
The formula to calculate the sum of the measures of the interior angles of a polygon is equal to
[tex]S=180(n-2)[/tex]
where
n is the number of sides of the polygon
In this problem we have a a quadrilateral
so
n=4
substitute
[tex]S=180(4-2)[/tex]
[tex]S=180(2)[/tex]
[tex]S=360\°[/tex]
