Question

the first angle of of a a triangle is one third its second angle, where as the third angle is 5 times the the first angle find the the major of all the angles of the triangle​

Answer 1

Answer:

let the first angle be x

by angle sum property :

=> x + 3x + 5x = 180°

=> 9x = 180°

=> x = 20°

therefore

first angle = 20°

second angle = 60°

third angle = 100°

Answer 2

Answer:

60°,20°,100°

Step-by-step explanation:

Let second angle be x

1st angle be 1/3x

3rd angle be 5/3x

x+1/3x+5/3x=180°

9x/3=180°

solving this

x=60°

1st angle is 60°

2nd angle is 20°

3rd angle is 100°
