Question

find the angle measure. m∠cod = ° classify the angle. ∠cod is a(n) angle.

Explanation:

Step1: Identify scale reading for rays

Read the degree - values where rays OC and OD intersect the protractor. Ray OC intersects at 140° and ray OD intersects at 70°.

Step2: Calculate the angle measure

Subtract the smaller degree - value from the larger one. $m\angle COD=140 - 70$.
$m\angle COD = 70^{\circ}$

Step3: Classify the angle

An acute angle is an angle whose measure is between 0° and 90°. Since $70^{\circ}<90^{\circ}$, $\angle COD$ is an acute angle.

Answer:

$m\angle COD = 70^{\circ}$
$\angle COD$ is an acute angle.
