16.
The second angle of a triangle is the dame size
as the first angle The thrid angle is 12
degrees larger than the first angle. How
large are the angle
​

Answer 1

Answer:

let three angles of triangle be x,y and z respectively.

from the given condition ,

x=y;

z=12+x;

we know that ,sum of three angles of triangles is 180

x+y+z=180

x+x+12+x=180

3x+12=180

x=168/3. x=56

so angles of triangle is 56,56,68 respectively
