Answer:

x = +/-10°

Step-by-step explanation:

[2(x+10)]°=

[2x + 20] =

[2x] = [-20]

2x/2 = -20/2

x = -10

(3x - 30)°

3x/3 = 30/3

x = 10

Answer:

The value of x = 50°

Step-by-step explanation:

As,

[2(x+10)]° & (3x-30)° both are Vertically opposite angles.

we know,

<em><u> vertically opposite angles are equal .</u></em>

so,

2(x+10) = 3x-30

⇒2x+20 = 3x-30

⇒3x-2x=20+30

∴x=50

∴The value of x = 50°
