Question

fill in the unknown angles marked in each of the following figures​

Answer 1

Answer:

20,40,120

Step-by-step explanation:

as we know the sum of the angles of a triangle is 180

now we get from the figure,

x+2x+6x=180

so,. 9x=180

x=20

2x =40

and 6x=120

hope it will hlp you

Answer 2

Answer:

this figure is a triangle.

here measure of angles given are 2x,6xand X

in a triangle the sum of all angles is 180°

there fore 2x + 6x + X = 180°

➡️ 9x = 180°

➡️ X = 20°

measure of 6x= 6×20

= 120

measure of 2x = 2×20

= 40

measure of X = 20
