Question

29) One of the exterior angles of the triangle is 80°& interior opposite angles are in the ratio
5:3. Find the angles of the triangle​

Answer 1

Using exterior angle property
5x+3x=80
8x=80
X=10
So angle are 50,30

Answer 2

Answer:

50° and 30°

Step-by-step explanation:

Let the opposite interior angles be 5x and 3x.

now as we know,

sum of two opposite interior angles is equal to exterior angle.

so, 5x +3x=80°

8x=80

x=80/8

x=10°

5x=5*10=50°

3x=3*10=30°
