Step-by-step explanation:
(let the angles of the triangle be 1x,4xand 7x)
so, a triangle has 180° measure.
therefore,1x+4x+7x=180°
so,12x=180°
x=180÷12
x=15
now actual values of them are :-
1×15=15°
4×15=60°
7×15=105°
this is your final answer thanks

Let the common factor be x
Ratio = 1 : 4 : 7
The sum of the angles of a triangle is equal to 180 degree
hence,
1x + 4x + 7x = 180
12x = 180
x = 180/12
x = 15
therefore the ratio will be =
1 multiplied by 15 that is 15
4 multiplied by 15 that is 60
7 multiplied by 15 that is 105
Final answer = 15 : 60 : 105
