Question

One of the exterior angles of a triangle is 140deegee and the interior opposite angles are in the ratioo 2:3.Find the angles of a triangle​

Answer 1

Step-by-step explanation:

2x+3x= 140

5x= 140

x= 28

first angle 28×2 = 56

second angle 28×3 = 84

#666

Answer 2

40°,56°,84°

Step-by-step explanation:

3rd interior angle opposite to exterior angle( 140° ) = 180-140 = 40°

sum of the angles of ∆ = 180°

40° + 2x + 3x = 180° => x = 140/5 = 28°

angles are 40° ,2x = 2(28)= 56°,

3x = 3(28) = 84°
