Question

find x in the given figure ​

Answer 1

Step-by-step explanation:

60+ 40 +( 5x -20)= 180

$100 + (5x - 20) = 180$

$(5x - 20) = 180 - 100$

$5x = 80 + 20$

$5x = 100$

$x = \frac{100}{5}$

$x = 20$

Answer 2

Answer:

x = 20°

Step-by-step explanation:

Sum of linear pairs = 180°

60° + 5x - 20° + 40° = 180°

5x + 80° = 180°

5x = 180° - 80°

5x = 100°

x = 100°/5

x = 20°
