Question

one of the angles of a triangle is half the sum of other two angles find the angle

Answer 1

let,
the three angles of a triangle be x,y,z
then,
according to the question
(x+y)/2=z
=>x+y=2z
we know that
x+y+z=180 degree
we can also write
2z+z=180 degree
=>3z=180 degree
=>z=180/3=60 degree
