Reference angle of -3 radians is α= - 171° 53 min 15 sec .
We know the formula for calculating circular arc
Let l=circular arc which ic according to central angle of the circle α
l=((2R π)/360)α Let l=1 radian and R=1 (unit circle with radius R=1)
1= ((2π)/360)α => α= 360/(2π)= 180/π= 57° 17 min 45sec
Angle of the 1 radian is equal to angle 57° 17min 45sec
According to this
angle of the -3 radians = -3 ( 57° 17min 45sec) = - 171° 53min 15sec
when you count in the clockwise direction.

Answer:
The width of bookcase D is 61 cm
The width of bookcase E is 61 cm
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Sum the widths of the three bookcases A, B and C
step 2
Subtract the sum of the three bookcases A,B and C from the total length of the wall
step 3
Divide that answer in step 2 by 2, and that will let you know the widths of D and E, because they may have equal widths
therefore
The width of bookcase D is 61 cm
The width of bookcase E is 61 cm
Answer:
87.5%
Step-by-step explanation:
Complete question -
75% of the people who eat at Doug's Diner order fish and 90% of the people who order fish also order fries. Given that 80% of all people who eat at Doug's order fries, what is the probability that a randomly chosen customer orders fries without fish?
Solution
Given
People who order fish at the Doug's Diner = 75%
Out of this 75%, 90% also order fries which means that nearly 67.5% ordered fries with the fish.
Given that, 80% of people dining at Doug's Diner order fries
Then percentage or people who ordered only fires and no fish = 80% - 67.5% = 12.5%
The probability of customers who ordered fish = 100 - 12.5% = 87.5%
