Question

if the angles of a triangle are in ratio 5:6:7 find angles

Answer 1

angles are in ratio=5:6:7
let these angles are=5x,6x,7x
5x+6x+7x=180°(angle sum property)
18x=180°
x=180÷18
x=10°
5x=5×10=50°
6x=6×10=60°
7x=7×10=70°

Answer 2

Hey,
Let the ratio of angle of triangle be x
Then your first angle =5x
"""""""Second""""""""=6x
""""""Third"""""""""7x
Now we know that the sum of all angle of triangle be 180°
Now, 5x+6x+7x=180°
18x=180°
X=10°
So first angle=50°
Second """""=60°
Third """"""""70°
