Answer:
The answer to your question is 90°
Step-by-step explanation:
Process
1.- Calculate the sum of the internal angles in a triangle
Formula = 180(N - 2)
N = 6
= 180(6 - 2)
= 180(4)
= 720° and each angle measures 720/6
= 120°
2.- Calculate the value of the internal angles of the triangle
In the triangle, one angle measures 120° and the other two measures
180 - 120 = 60° but these angles are equal because the triangle is isosceles.
Then each small angle in the triangle measures 30°
3.- Calculate x
x = 120 - 30
x = 90°
