Question

Find value of x in the following
Give answer in image form​

Answer 1

$\large\bold{\underline{\underline{Solution:-}}}$

We know that,

Sum of angles on a straight line = $180°$

:⟼  $x + (x + 40°) = 180°$

:⟼  $x + x = 180° - 40°$

:⟼  $2x = 140°$

:⟼  $x = \frac{140°}{2}$

:⟼  $x = 70°$

Therefore, the value of $x$ is $\boxed{ 70° }$.

Answer 2

Answer:

ln a straight line is always 180°

so x+ x+40°=180

2x=180°-40°

2x=140°

x=140°/2

x=70
