Question

6] In fig. AOB is a straight line, AOC = (3x + 20) ° and BOC = (4x -36) °, then the value of x is______​

Answer 1

Answer:

Plz Try giving figure.

Here ,

angle AOC + angle BOC = 180° [angle sum property]

(3x + 20) + ( 4x - 36) = 180°

3x + 4x +20 - 36 = 180°

7x - 16 = 180°

7x = 180 + 16

x = 196 \ 7

x = 28 { answer )

Answer 2

Answer:

x = 56

Step-by-step explanation:

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

4x - 3x = 36 +20

1x = 56

x = 56 / 1

x = 56

verification :

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

( 3 ( 56 ) + 20 ) = ( 4(56) - 36 )

( 168 + 20 ) = ( 224 - 36 )

188. = 188
