angles of a triangle are 1x, 3x, 5x

x+3x+5x = 180⁰

9x = 180⁰

x = 20⁰

angles of triangle are 20⁰, 3×20= 60⁰, 5×20= 100⁰

Answer 2

Answer:

180degree

Step-by-step explanation:

The ratio 1:3:5 by doubling each number is the same as 2:6:10 and the big one 10 is 10/(2+6+10) = 10/18 of the total, so multiplying top and bottom by 10 gives 100/180, so the biggest angle is 100° since the sum of all angles must be 180°.
