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
