Question

the angles of a triangle x,y,z are in descending orders. if 2x-y=100=3y-2z, its smallest angle is ?

Answer 1

hiii friend,

given 2x-y=3y-2z

→2x+2z=4y

→x+z=2y--------(1)


given x,y,z are angles of triangle

x+y+z=180

by (1)

3y=180

→y=60

and also given 3y-2z=100

→180-2z=100

→z=40

since x,y,z are in descending order ...its smallest angle is z which is 40°


I hope this will help u :)
