Answer:
The value of x = 30°
Step-by-step explanation:
The value of first angle = ( 2 x)
The value of the second angle = ( x + 30)
Now, the given angles are VERTICAL ANGLES.
Also, by the definition, the VERTICAL ANGLES ARE CONGRUENT.
So, First Angle = Second Angle
⇒ (2 x ) = ( x + 30 )
or, 2 x - x = 30
⇒ x = 30
Hence, the value of x = 30°.
