Answer:
87°, 68°, and 25°
Step-by-step explanation:
All the angles in a triangle will equal to 180° so with knowing this you can create the equation...
(7x-11)° + (2x-3)° + (5x-2)° = 180°
(14x-16)° = 180°
14x = 180° + 16°
14x = 196°
x = 14°
Knowing x you can substitute this value into each angle.
7(14)-11 = 87°
5(14)-2 = 68°
2(14)-3 = 25°
To confirm that these are the right answers you can add all these angles to see if they equal to 180°.
87° + 68° + 25° = 180°
Answer:
It has four lines of symmetry and four sides
