Question

20. Use the adjacent figure, to find angle x and its supplement.
3x
4x
2x
What’s the degree

Answer 1

Step-by-step explanation:

4x+3x+2x+x=180

10x=180

x=180/10

x=18

so, 4x=4*18=72

3x=3*18=54

2x=2*18=36

supplement of 4x=180-72=108

supplement of 3x=180-54=126

supplement of 2x=180-36=144

supplement of x=180-18=162

Answer 2

Answer:

this is your answer

Step-by-step explanation:

In the given fig.

x + 2x + 3x + 4x = 180° (Straight angle)

⇒ 10x = 180°

⇒ x = 180°/10 = 18°

∴ x = 18°

Its supplementary angle = 180° - 18°

= 162°
