Answer:
70°
Step-by-step explanation:
1st angle = 55°
2nd angle = 55° [ as it is a isosceles triangle]
3rd angle = 180° - (55° + 55°) = 180° - 110° = 70°

↠ One of the two equal angles of an isosceles triangle measures 55°. Find the measure of all the angles of triangle.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
↠ Sum of all interior angles of triangle is equal to 180°
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
↠ Measure of one of the equal angle = 55°
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Let's Start !
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Let the angles be ∠A, ∠B, ∠C
And ∠B = ∠C = 55°
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
∴ By given angle sum property
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
↠ Sum of all interior angles = 180°
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Hence Verified.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
