Question

of the three angles of a triangle, the second is one third the first and the thirs is 26° more then the first. how many degrees are there is each angle?

Answer 1

let first angle=x
second=x/3
third=x+26
total=x+x/3+x+26=180
2x+x/3=180-26
7x/3=154
x=154×3/7=66
first=66
second=66/3=22
third=66+26=92
