Question

5th one
find the value of X​

Answer 1

Answer:

x=28

Explanation:

As the angles are in a straight line, they sum up to 180 degrees.

According to the question,

=>(3x+20)+ (4x-36)= 180

=>(3x+4x) +(20-36)= 180.

=> 7x-16=180

=> 7x=180+16=196

x= 196/7= 28

Answer 2

Answer:

x = 28°

Step-by-step explanation:

POQ is a straight line and ∠1 and ∠2 are angles on the same line.

therefore,   ∠1+∠2 = 180 (linear pair of angles)

               (3x+20)+(4x-36)= 180

               3x+4x+20-36= 180

              7x -16 = 180

                   7x = 180+16 =196

             ⇒ x = 196/7 = 28.
