Question

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

m∠lhn =
(type a whole number.)

help me solve this view an example get more help

Explanation:

Step1: Identify angle measurement

Read the protractor. The angle $\angle LHN$ has one - side along the vertical line (at 90 - degree mark) and the other side along the outer - scale of the protractor at 130 degrees.

Step2: Calculate the angle measure

The measure of $\angle LHN$ is found by subtracting the measure of the right - angle (90 degrees) from the outer - scale reading. Since the vertical line is at 90 degrees and the other side is at 130 degrees on the outer scale, $m\angle LHN=130 - 90=40^{\circ}$.

Step3: Classify the angle

An acute angle is an angle whose measure is between 0 and 90 degrees. Since $40^{\circ}<90^{\circ}$, $\angle LHN$ is an acute angle.

Answer:

$m\angle LHN = 40^{\circ}$, Acute
