Question

use the diagram. find the measure of ∠hdj. then classify the angle as \acute,\
ight,\ \obtuse,\ or \straight.

m∠hdj =
(type a whole number.)

help me solve this view an example get more help -

Explanation:

Step1: Read angle measure from protractor

Read the measure of $\angle HDJ$ from the outer - scale of the protractor. The ray $DJ$ is on the 0 - degree mark of the outer - scale and the ray $DH$ intersects the outer - scale at 50 degrees. So, $m\angle HDJ = 50^{\circ}$.

Step2: Classify the angle

An acute angle is an angle whose measure is between $0^{\circ}$ and $90^{\circ}$. Since $50^{\circ}<90^{\circ}$, $\angle HDJ$ is an acute angle.

Answer:

$m\angle HDJ = 50^{\circ}$, Acute
