Question

find the measure of each exterior angle of an equilateral triangle? plzzzzz fast

Answer 1

each interior angle of an equilateral triangle=60°
thus,
exterior angle =>
60+x=180
x=180-60
x=120°

hope it helps.........

Answer 2

each exterior angle of an equilateral Δ is 120°..... because we know that the sum of two corresponding angles is equal their corresponding exterior angles.... so,

60°+60°= 120°
