Question

if 7x and 3x. are forming a linear pair then x is?? ​

Answer 1

Answer:

7x + 3x = 180 (sum of the angles of linear pair is 180 degrees)

10x = 180

x = 180/10

x = 18

Answer 2

Value of x = 18

GIVEN :- 7x and 3x are forming a linear pair.

TO FIND :- value of x

SOLUTION :-

As we know, the sum of angles of a linear pair is always equal to 180°.

Therefore,

$7x + 3x = 180$

By adding both the x

$10x = 180$

By multiplying 10 both sides

$\frac{10x}{10} = \frac{180}{10}$

$x = 18$

Hence, value of x = 18

Note:- In geometry, linear pair of angles are adjacent angles that are formed when two lines intersect at a point. The sum of angles of a linear pair is 180°.
