<PRE><B>Question 228463</B>
dear student,
let first angle is x degree and second(as given instruction)=4x and third angle= 2x+5
so now we know addition of 3 angles of a triangle is 180 degree so
making addition of above angles 
x+4x+(2x+5)=180 degree
x+4x+2x+5= 180degree
7x+5=180 degree
7x= 180-5
 7x=175
x=175/7
so x= first angle= 25 degree
second =4x=100 degree
and third 2x+5= 55 degree
thanks
faithfully
