Question

of the three angles of a triangle one is three times the smallest and the other is 5 times the smallest find the angles​

Answer 1

Answer:

20 , 60 , 100

Step-by-step explanation:

Let the smallest angle be x.

the other angles are 3x, 5x.

Sum of angles of triangle = 180

x + 3x + 5x = 180

9x = 180

x = 180/9 = 20

5x = 5 * 20 = 100

3x = 3 * 20 = 60

Answer 2

Answer:

let the angles of triangle be X,3x and 5x

as we know

sum of all interior angles of a triangle is 180°

x + 3x +5x =180

9x=180

X=20

angle 1=X=20°

angle 2=3x=3×20=60°

angle3=5x=5×20=100°
