Answer:

60 degrees

Step-by-step explanation:

The sum of the angles in a triangle are 180 degrees. The angles look the same size, so divide 180 by 3, and you get 60 degrees

Answer:

x = 54°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5, thus

sum = 180° × 3 = 540°

Each interior angle is therefore 540° ÷ 5 = 108°

Since the triangles are congruent then x = 108° ÷ 2 = 54°
