The value of ∠MHJ is 50°. Therefore, option B is the correct answer.
We need to find the value of ∠MHJ.
What are vertically opposite angles?
Vertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines. Vertically opposite angles are equal to each other.
Here, ∠MHJ and ∠KHL are two vertically opposite angles.
So, (x+15)°=(2x-20)°
⇒x=35°
Now, ∠MHJ=(2x-20)°=50°
Therefore, option B is the correct answer.
