Answer 1

Solution :-

Answer :-

X = 50°

_______________________

To Find :-

The value of X.

Given :-

AOB is a straight line [ Therefore AOB = 180° ]

Step By Step Solution :-

AOB is straight line.

So, It makes 180°.

$x + 10 + x + x + 20 = 180 \\ \\ 3x + 30 = 180 \\ \\ 3x = 180 - 30 \\ \\ 3x = 150 \\ \\ x = 50$

Therefore X = 50°.

_________________________

Check :-

$x + 10 + x + x + 20 = 180 \\ \\ 50 + 10 + 50 + 50 + 20 = 180 \\ \\ 180 = 180$

Therefore L. H. S. = R. H. S.

Extra Information :-

• Straight line always make 180°
• 90° angle is also known as Right angle.
• Complementary angles makes 90°
• Supplementary angles makes 180°
• Angle bisector divides the angle into two equal angles.
