Question

16.
Sum of two angles forming a linear pair is (3x -8°) and (x + 20°). Find the value of x.

Answer 1

Step-by-step explanation:

Sum of a linear pair is 180 degrees.

So,

(3x-8) + (x+20) = 180

-24 + (x+20) = 180

x+20= 180+24

x+20 = 204

x = 204 - 20

x= 184

Answer 2

Answer:

48

Step-by-step explanation:

sum of two angles of a linear pair = 180°

(3x -8°) + (x + 20°)=180°

4x - 12° = 180°

4x= 180°+12°

4x=192°

x=192°/4°

x=48°
