Question

Find the value of x in the above figure :
3х - 10°
2х - 20°​

Answer 1

$\sf \Large Solution!!$

3x - 10° + 2x - 20° = 180° (Linear Pair)

5x - 30° = 180°

5x = 180° + 30°

5x = 210°

x = 42°

Answer 2

Step-by-step explanation:

(3х - 10°) +( 2х - 20°) = 180 ( sum of the linear pair is 180 °)

3x - 10 + 2x -20 = 180

5x - 30 = 180

5x = 180 + 30

5x = 210

x = 210

5

x = 42

3x - 10 = 3 ( 42 ) - 10

= 126 - 10

= 116

2x - 20 = 2 ( 42) - 20

= 84 - 20

= 64
