If one exterior angle is 110, then opposite interior angle to it is of (180-110=70°)
Then,
Let the other two equal interior angles be x and x, then
x+x+70=180
2x=180-70
2x=110
x=55
All interior angles are 55,55,70

Step-by-step explanation:
as, exterior angle of a triangle is equal to the sum of the two opposite interior angles
so,
→ x + x + 10 = 110
→ 2x + 10 = 110
→ 2x = 110 - 10 = 100
→ x = 100/2 = 50
→ x = 50
therefore value of x is 50.
hope this answer helps you dear...!
