Question

if one exterior angle of a triangle is 140. and interior opposite angles are in ratio 3:4. find the angles of the triangle

Answer 1

Answer:

60 and 80

Step-by-step explanation:

As,

we take a common factor x =

3x + 4x = 140

7x = 140

x = 140/70

x = 20

Now,

We multiply 3 and 4 to 20

3 x 20 = 60

4 x 20 = 80

Hope this helps
