Let smaller angle be x
Let larger angle be 20 + x
Sum of two supplementary angles = 180°
x + 20+ x = 180°
2x + 20 = 180
2x = 180-20 = 160
x = 160/2 = 80
Smaller angle = x = 80°
Larger angle = 20 + x = 20 + 80 = 100°
I hope it is helpful:D
Is 15 an option for this question
Answer:
0.28
Step-by-step explanation:
Refer the attached figure
Given :
People who live in their hometown and graduated from the college =8
People who do not live in their hometown and graduated from the college = 10
People who did not graduate from college and lives in home town = 6
People who did not graduate from college and do not live in home town = 4
To Find : Among people who do not live in their hometown, what is the relative frequency of not graduating from college?
Solution :
The total no. of people who do not live in home town whether they are graduated or not graduated = 14
People who did not graduate from college and do not live in home town = 4
Thus Among people who do not live in their hometown the relative frequency of not graduating from college :
People who did not graduate from college and do not live in home town/total no. of people who do not live in home town whether they are graduated or not graduated
⇒
⇒
⇒
Thus , Among people who do not live in their hometown the relative frequency of not graduating from college = 0.28
