Answer 2

Step-by-step explanation:

given that ratio of angles is 1:3:5

then let the angles be $x$,$3x$,$5x$

we know that sum of all angles in a triangle is $180^0$

therefore; $x+3x+5x=180^0$

                $9x=180^0$

                $x=\frac{180^0}{9}$

                $x=20^0$

by knowing the value of x

the values of the angles are $20^0,3(20^0),5(20^0)$

i.e $20^0,60^0,100^0$

Therefore the greatest angle is $100^0$
