Question

find x, if l || m
plzzz reply fast​

Answer 1

GIVEN :-

• l || m.
• one of the angle is 105°.

TO FIND :-

• The value of x.

SOLUTION :-

☨ Note: Refer to attachment for better understanding.

➣ ∠1 = 105°

Reason :- corresponding a angles

➣ ∠1 + x = 180°

Reason :- Linear pair.

➣ 105° + x = 180°

➣ x = 180° - 105°

➣ x = 75°

Hence the value of x is 75°.

ADDITIONAL INFORMATION :-

⓵ Parallel Lines :- Two or more lines in the plane which do not meet anywhere in the plane . that is the distance between two lines is same in each and every point .

⓶ Transversal :- A line whitch intercert two or more lines at distinct point.

Answer 2

Question :

If l || m. Find the value of x.

Añswer :

∠1 = 105° (Corresponding angles)

➞ 105° + x = 180° (Linear pair)

➞ x = 180° - 105°

.°. x = 75°

________________________....

▪Corresponding Angles :-

When a line (transverse) intersects parallel lines corresponding angles are formed.

Corresponding angles are congruent [equal to each other]

▪Linear Pair :-

Linear pair are two adjacent angles that create a line. The two angles are supplementary [add up to 180°].
