Question

In figure the value of x is​

Answer 1

Answer:

(b) 130°is the correct value of x.

Answer 2

Given,

Exterior angle, $\[110^\circ ,120^\circ ,x^\circ \]$

Solution,

Know that the sum of exterior angles of a triangle is $\[360^\circ \]$

$\[\begin{array}{l}110^\circ + 120^\circ + x^\circ = 360^\circ \\ \Rightarrow 230^\circ + x^\circ = 360^\circ \\ \Rightarrow x^\circ = 130^\circ \end{array}\]$

Hence the value of x is $\[130^\circ \]$
