let the angles 3x and 7x and given angle is 80
we know that
sum of all the angles in a triangle= 180( angle sum property of triangle...)
therefore 10x +80= 180
10x = 100→ x = 10
the angkes are 30 and 70...hope it helps plz mark as brainliest....

Given one angle is 80°
Let two angles be 3x and 7x
Sum of triangle=180°
80°+3x+7x=180°
80°+10x=180°
10x= 180°-80°
10x=100°
x=100/10=10
Now put the value of x in 3x and 7x
First angle=80°
Second angle= 3x=3×10=30°
Third angle =7x=7×10=70°
Hope it will be helpful for you
