Can you check my work ?

celia is staring at the clock waiting for school to end so that she can go to track practice. she notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle.

part 1: how many radians does the minute hand move from 1: 25 to 1: 50? (hint: find the number of degrees per minute first.)

my part one:
(360degrees/60minutes = 6 degrees per minute.)
1: 25 to 1: 50 is 25 minutes. 25 x 6 = 150.
150pi/180 = 5pi/6,

Me #1 using vocabulary words, including the word “congruent”, state why the measure of angle d is 120 degrees. #2 what is the measure of angle e and why?
