Question

Find the value of $x$ in each of the following figures:

Answer 1

Compute the required value:

We know that, vertically opposite angles are equal.

So, from the figure, we get;

$$\begin{gathered} \Rightarrow 3x=105° \\ \Rightarrow x=\frac{105}{3} \\ \Rightarrow x=35° \end{gathered}$$ [ Dividing both sides by $3$ ]

Hence, the value of $x$ is $35°$.
