Question

Find the supplementary of
​

Answer 1

Answer:

The sum of the three angles of a triangle is 180.

So, 2x + 3x + 4x = 180

(2 + 3 + 4) x = 180

9x = 180

x = 20.

So, the three angles of the triangle are

2x -> 40

3x -> 60

4x -> 80

40 + 60 + 80 = 180.

Answer 2

sum of those all angles is 180°

so ,

$2x + 3x + 4x + 6x = 180 \\ \\ 15x = 180 \\ \\ x = \frac{180}{15} = 12 \degree$

2x = 2*12 = 24°

3x = 3*12 = 36°

4x = 4*12 = 48°

6x = 6*12 = 72°
