Question

An exterior angle of a triangle is 100° and the interior opposite angles are in the ratio of 3:1, find the angles of the triangle.plz help as fast you can I need it plz with method​

Answer 1

Answer:

Step-by-step explanation:

Let the no be = 3x and 1x

3x + x = 100 ( Exterior angle = sum of opposite interior angles)

4x = 100

x = 100/25

=x=25

3x = 75

Answer 2

Answer:

the first angle is : 75°

the second angle is : 25°

the third angle is : 80°

Step-by-step explanation:

Exterior angle = 100°

3x + x = 100°

4x = 100°

x = 25°

So, the angles are : 3 × 25° = 75°

the second angle is : 1 × 25° = 25°

the third angle is : linear pair 180° - 100° = 80°
