Question

find the value of x. please tell urgent​

Answer 1

Answer:

Given:

L।।M and T is transversal

Now,as we when two lines are parallel then there corresponding angles are equal.

Therefore,

=> (2x+20)⁰ = (3x-10)⁰

=> 2x-3x = -10⁰-20⁰

=> -x = -30⁰

=> x = 30⁰

Therefore the value x is 30⁰.

Answer 2

✦Answer ✦

As we all know :-

By using the corresponding angle property

↠ ( 2x + 20 )° = ( 3x - 10)° { by C.A.P }

↠ 2x - 3x = -10° - 20°

↠ -x = - 30°

$\large{\boxed{\bold{x\:=\:30 }}}$

Additional Notes :-

★ What is Vertically Opposite Angle?

➹ Two angles are called a pair of vertically opposite angles, if their arms form two pairs of opposite rays.

★ What is Corresponding angles?

➹ The angles which occupy the same relative position at each intersection where a straight line crosses two others are known as corresponding angles. If the two lines are parallel, the corresponding angles are equal.

★ What is Linear pair of angles?

➹ Two adjacent angles of which different arms are opposite rays are called linear pair of angles.

★ What is Supplementary angles?

➹ If the sum of two angles is 180°, these are called supplementary angles. For example, two angles measuring 62° and 118° are supplementary angles, because 62° + 118° = 180°.

★ What is Complementary angles?

➹ Two angles, the sum whose measure is 90°, are called complementary angles. For example, angles measuring 30° and 60° are complementary angles as their sum is equal to 90° (30°+ 60° = 90°).

★ What is Parallel lines?

➹ Two different lines in a plane are said to be parallel, if there is no point common in them even through these lines are extended on both sides to any extent.
