QuestionIn triangle $D E F, m \angle E$ is three times $m \angle D$, and $m \angle F$ is $9^{\circ}$ less than $m \angle E$. What is the measure of each angle?
Find the $m<D=$ $\square$ Find the $m<E=$ $\square$ Find the $\mathrm{m}<\mathrm{F}=$ $\square$

Studdy Solution
Verify the solution by checking the sum of the angles:
$$m \angle D + m \angle E + m \angle F = 27^\circ + 81^\circ + 72^\circ = 180^\circ$$
The sum is correct, confirming the solution.
The measures of the angles are: - $m \angle D = \boxed{27^\circ}$ - $m \angle E = \boxed{81^\circ}$ - $m \angle F = \boxed{72^\circ}$
