A analog clock (with hour and minute hands) is set to 5:00 P.M. After 30 min, what will the measure of the major arc formed by h
VikaD [51]

Answer:

180 degrees

Step-by-step explanation:

Given

Time = 5:00pm

Required

The measure of the major arc, 30 minutes after

First, we calculate the time after 30 minutes

Time = 5:00pm +30\ mins

Time = 5:30pm

At 5:30pm, the hour and the minute hand will be directly opposite each other.

In other words, the hands divide the time into two equal parts (180 degrees each)

At this point, there is no major or minor arc as both sides have the same measurement

<em>Hence, the measure of the arcs is 180 degrees</em>
