Question

one angle of a trangle is 60 and otther angle are equal , find the third angle

Answer 1

60

as sum of anges of triangle is 180 if 0ne is 60 and other two are equal and left is 180-60 is 120 half of which is 60 and then all are 60

this is and equatorial triangle

p.s. i do not know how to use degree sign so i just gave numbers

Answer 2

Given one Angle is 60°
and by angle sum property of traingle the sum of other two angles
=180-60=120°
now given that both the angles are equal
let one Angle be x then other be also x
sum =120°
2x=120°
x=60°
both the angles are 60° hence it is an equilateral traingle
So third angle would be 60°



hope this helps you...
