Answer 1

Answer:

Hello mate,

let the first angle be x,

then,according to question,

second angle=x/3

and the third angle =x+26

Now ,angle1 +angle 2+angle3=180 [sum of interior angles of triangular is 180°]

x+x/3+x+26=180

3x+x+3x+78/3=180

7x+78=180*3

7x+78=540

7x=540-78

x=462/7

x=66

Then,angle 1=66

angle 2=66*1/3=22

angle3=66+26=92
