Question

One side of triangle is produced making an extirior angle of 160.if the intirior opposite angle are in the ratio 2 : 5 . find the measure of each angle of the triangle​

Answer 1

Answer:

Let the interior angles be 2x and 5x

so using property, exterior angle of a triangle is equal to sum of interior opposite angles

2x + 5x = 160

7x = 160

x = 160/7

So interior angles are 320/7, 800/7
