Answer 1

Hi!
Here is your solution...

Given ,one angle measure =60°=a
other 2 angles measure= (2×60°)
=120°(b+c)
let 3 angle be- a, b ,c



we know that the sum of three angles of a triangle is 180 degree

angle a+angle b+angle c=180°
60°+b+c=180°
b+c=180°-60°
=120°

so,b=60°
c=60°

hope it helps you...✌️
