Hope it helped!
Answer: 270 degrees
Step-by-step explanation: Imagine the clock to be one circle (which it is). In this method we need to you visualise and do a little bit of math. Let's ask a few questions.
Question 1: How many segments is the clock divided into?
Answer: 4, those segments are 3, 6, 9 and 12.
Question 2: Using the segments on the clock, how can we divide the circle so that each segment gets an equal amount of degrees?
Answer: 90 degrees
degrees in a circle/segments in a clock
=360/4
=90
Question 3: What segment is 45 minutes?
Answer: We know that when the minute hand comes to 9 (from 12), then 45 minutes have passed.
Question 4: What segment is 9
Answer: The 3rd segment
Question 5: How many degrees is the third segment.
Answer: 270 degrees
the segment*amount of degrees in a segment
=3*90
=270 degrees
And that's your answer.
