Pls mark as brainlist

Step-by-step explanation:

Let, A, B and C be the angles of ΔABC A = B = C (Given) We know that, ∠A + ∠B + ∠C = 180° ∠A + ∠A + ∠A = 180° 3∠A = 180° ∠A = 60° Therefore, ∠A = ∠B = ∠C = 60° Thus, each angle is equal to 60°Read more on Sarthaks.com - https://www.sarthaks.com/1071590/if-all-the-three-angles-of-triangle-are-equal-then-each-one-of-them-is-equal-to-90-45-60-30

Answer 2

Answer:

60

Step-by-step explanation:

Let the three equal angles of triangle be x. Then,

x+x+x = 180 (Being the sum of the interior angles of a triangle)

or, 3x = 180

or, x = 180/3 = 60
