if one of a triangle is 80° and the other two angles are in the ratio 3:7

Hastdidx: following

sanya16185: wat following

rakeshchaudhary9450: The sum of all side in triangle is 180. There are three sides in triangle if one side is 80 then the sum of other two side is 100. If the ratio of other two side is 3:5.let 3x+7x=100,10x=100,x=10 ,so the value of 3x and 7x is 30 and 70.

Mate maye be it will help u....!!!
- if one angle =80 deg.. given
than other two = 180-80= 100 for both angles
and your ratio is 3:7 which is for both angles
so, 3+7 give 10 which is equal to the both angles
10----------> 100
1---------->10
so, for the ratio 3-----> 3*10= 30 deg...
and for ratio 7------> 7*10 =70 deg..
so , 30 and 70 is ur answer..

Hastdidx: you made it easy man

$angle \: 1 = 80 \\ let \: other \: two \: angles \: be \: 3x \\ and \: 7x \\ = > 80 + 3x + 7x = 180 \\ = > 10x = 100 \\ = > x = 10. \\ \\ so \: other \: two \: angles = > \\ angle \: 2 = 3x = 30 \: and \\ angle3 = 7x = 70$
