Answer:
30,70
Step-by-step explanation:
Let the Angles be 3x and 7x
We know that sum of all angles in a triangle = 180 Degrees
3x + 7x + 80 = 180
By transposing 80 to the other side we get
10x = 180 - 80
10x = 100
By transposing 10 to the other side we get
x = 10
The angles are :
3x = 3 x 10 = 30 Degree
7x = 7 x 10 = 70 Degree

Answer:
30 degree and 70 degree
Step-by-step explanation:
Triangle = 180 degree
one angle= 80 degree
other two angles= 180-80= 100 degree
ratio= 3:7
Let the number be 'x'
3:7 = 100
3x:7x = 100
= 3x + 7x = 100
10x = 100 degree
x = 100/10
x = 10
Therefore,
3x= 3*10
= 30 degree
7x= 7*10
= 70 degree
Therefore, 30 degree and 70 degree
