Question

one of exterior angles of a triangle is 130 degree and interior opposite angle are in the ratio 2.3 find the angles of the triangle​

Answer 1

Answer:

Let interior opp angles be 2x and 3x

exterior angle = sum of interior opp angles

130 = 2x + 3x

5x = 130

x = 26

4.4

Answer 2

Step-by-step explanation:

let the interior angles be = 2x and 3x

sum of interior angles = exterior angles

2x+3x = 130°

5x = 130°

x = 26°

let angle one = 26×2= 52°

let angle two = 26 × 3 = 78°

therefore, angle three = 180°-(52+78)°

=180°-130° = 50°

angles of triangle = 78°, 52° , 50°
