Question

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

m∠khm =
(type a whole number.)

Explanation:

Step1: Read angle from protractor

Use the inner - scale of the protractor. The ray $\overrightarrow{HK}$ passes through 120 and $\overrightarrow{HM}$ passes through 40.

Step2: Calculate angle measure

$m\angle KHM=120 - 40=80^{\circ}$

Step3: Classify the angle

Since $0^{\circ}<80^{\circ}<90^{\circ}$, it is an acute angle.

Answer:

$m\angle KHM = 80^{\circ}$, Acute
