What Is The Value Of X A 30 B 45 C 55 D 60 class=

Sagot :

Answer:

B

Step-by-step explanation:

x and 3x are adjacent angles and sum to 180° , then

x + 3x = 180

4x = 180 ( divide both sides by 4 )

x = 45

The answer is 45:
1.) The top angle of 3x would be the same as the bottom as opposite angles with parallel lines are equal.
The left and right angles would also be the same for the same reason.
Therefore, 3x + 3x + x + x = 8x
2.) All the angles around the centre ‘R’ add up to 360° , so to workout x you workout out 360 divided by 8 which equals 45°
HOPE THIS WAS HELPFUL AND EASY TO UNDERSTAND :)
