Answer 1

Answer:

Given :   l parallel to m

To Find :   value of X

Solution  :

Properties of angles formed by transversal line  with two parallel lines :

• Corresponding angles are congruent.  

• Alternate angles are congruent.  ( Interiors & Exterior  both )  

• Interior angles are supplementary. ( adds up to 180°)

x  and 126°  are alternate interior angles

Hence value of x = 126°

Answer 2

Answer:

$= > x = 8°$

Step-by-step explanation:

$∵ \: sum \: of \: all \: angles \: on \: a \: straight \: line \: = 180° \\ ∴ \: (4x + 30)°+ (5x - 10)° + (6x + 40)° = 180° \\ 4x + 30°+ 5x - 10° + 6x + 40° = 180°\\ = > 15x + 60° = 180 °\\ = > 15x = 120 ° \\ = > x = 8°$
