Question

The angle of the triangle are such that one angle is double of the second and the third angle is thrice of the 1st . find all the angles of the triangle ...​

Answer 1

Answer:

angle 1 = 2x

angle 2 = x

angle 3 = 6x

Step-by-step explanation:

angle 1 = 2x

angle 2 = x

angle 3 = 6x

according to sum off all angles of triangle,

2x + x + 6x = 180*

9x = 180*

x = 20*

therefore,

all three angles :-

angle 1 = 2x = 2 X 20 = 40*

angle 2 = x = 20*

angle 3 = 6x = 6 X 20 = 120*

Verify,

40+20+120 = 60+120 = 180

Hence our answer is correct

Answer 2

Answer:

Step-by-step explanation:

LET,

angle 1 = 2x

angle 2 = x

angle 3 = 6x

2x + x + 6x = 180( sum of angles in triangle is 180⁰)

9x = 180

x = 20

therefore,

all three angles :-

angle 1 = 2x = 2 X 20 = 40

angle 2 = x = 20

angle 3 = 6x = 6 X 20 = 120
