Answer:
0.5
Step-by-step explanation:
divide 2.5 and 5 since they are equal sized bottles.
The answer is C 15 because 37+15=52, 52+15=67, 67+15=82
we are given
Point A lies on the circumference of the unit circle
so, we can write equation of circle as

now, we are given

so, we can plug it in equation and find y



Since, point-A lies in first quadrant
so, both x-value and y-value will be positive
so, we get
.............Answer
2x+7x= 180
9x=180
x=20
Plug the x value in to both expressions
2(20)=40
7(20)=140
Final answer: 40 degrees, 140 degrees
