<PRE><B>Question 206405</B>
Let  1st  angle  = 4x,,,,,,and  2nd  angle  = 5x
.
Then  3rd  angle  is  the  sum  of  the  first  2  or  ,,,,4x+5x = 9x
.
remember  that  the  sum  of  the  angles  of  a  triangle  is  180
.
4x + 5x + 9x + 180
.
18 x = 180  
.
x=10
.
The  1st  angle  = 4x = 40,,,2nd  angle = 5x =50,  and  3rd  angle =9x = 90
.
check,,,,40 +50 +90 = 180 ok,  ratio  of  ist  2  angles  is  40/50 = 4/5,,ok
