Question

4) FIND x in the following fiGURE​

Answer 1

To find

value of x from the above attachment

Solution

❖Linear pair is formed when two lines intersect each other at the same point.

❖ The sum of angles in Linear pairs is 180°.

$\sf{ : \implies3x + x + 40 \degree} = 180 \degree \\ \\ \sf{ : \implies4x + 40 \degree = 180 \degree} \\ \\ \sf{ : \implies4x = 180 - 40 = 140 \degree} \\ \\ \sf {: \implies x= \frac{140}{4} = 35 \degree}$

Facts that Matters!!

✔️Line segment- line segment is a part of a line which has two endpoints.

✔️Ray - ray is a part of a line which has one endpoint and extends infinity in one direction.

✔️ perpendicular lines- when two lines make 90 ° angle they are said to be perpendicular lines.

✔️ parallel lines- lines are set to be parallel when they do not intersect at any point.
