Question

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

Explanation:

Step1: Identify scale readings

Read the scale values for rays OC and OE. Ray OC is at approximately 140° and ray OE is at approximately 50°.

Step2: Calculate angle measure

Subtract the smaller scale - value from the larger one. \(m\angle COE=140 - 50\).
\(m\angle COE = 90^{\circ}\)

Step3: Classify the angle

An angle with a measure of 90° is a right - angle.

Answer:

\(m\angle COE = 90^{\circ}\)
\(m\angle COE\) is a right angle.
