Is the angle formed by MH and MJ acute, obtuse, or straight?

The angle shown next to "14." is visually larger than $90^\circ$ but less than $180^\circ$. 14. The angle shown is an obtuse angle.

From the diagram, the measure of $\angle H M J$ is given as $60^\circ$.
Since $60^\circ < 90^\circ$, it is an acute angle.
$\angle H M J = \boxed{\text{}60^\circ\text{}}$ (Acute angle)

From the diagram, the measure of $\angle J M K$ is given as $30^\circ$.
Since $30^\circ < 90^\circ$, it is an acute angle.
$\angle J M K = \boxed{\text{}30^\circ\text{}}$ (Acute angle)

$\angle H M K$ is the sum of $\angle H M J$ and $\angle J M K$.

Since $\angle H M K = 90^\circ$, it is a right angle.
$\angle H M K = \boxed{\text{}90^\circ\text{}}$ (Right angle)

Let L be the point on the leftmost ray. $\angle L M J$ is the sum of $\angle L M H$ and $\angle H M J$.

Since $90^\circ < 110^\circ < 180^\circ$, it is an obtuse angle.
$\angle L M J = \boxed{\text{}110^\circ\text{}}$ (Obtuse angle)

Let L be the point on the leftmost ray and N be the point on the rightmost ray. $\angle L M N$ is the sum of all angles along the straight line.

Since $\angle L M N = 180^\circ$, it is a straight angle.
$\angle L M N = \boxed{\text{}180^\circ\text{}}$ (Straight angle)
