Find x° = ?

The angle $95^\circ$ is an exterior angle to the triangle at the top vertex. An interior angle and its adjacent exterior angle form a linear pair, meaning their sum is $180^\circ$.
Let the interior angle at the top vertex be $\alpha$.

$$\alpha = 180^\circ - 95^\circ$$ $$\alpha = 85^\circ$$

The exterior angle of a triangle is equal to the sum of its two opposite interior angles. In this case, $x^\circ$ is the exterior angle, and the two opposite interior angles are $45^\circ$ and $\alpha$.

$$x^\circ = 45^\circ + \alpha$$

Substitute the value of $\alpha$ from Step 1:

$$x^\circ = 45^\circ + 85^\circ$$ $$x^\circ = 130^\circ$$

The value of $x$ is:

$$130$$
