Question

in figur find the value of x​

Answer 1

We know that at a point the angle measured is 360°

$\therefore \quad We \: have$

$\Rightarrow \qquad 4x + 2x + x + 150^{\circ} = 360^{\circ} \\ \Rightarrow \qquad 7x = 360^{\circ} - 150^{\circ} \\ \Rightarrow \qquad 7x = 210^{\circ} \\ \Rightarrow \qquad x = \frac{210^{\circ}}{7} \\ \boxed{x = 30^{\circ} }$

ANSWER: 30°
