18a:16 18b:32 % means out of 100
C = 2 pi r
c = 2(3.14)(1/4)
c = 1/2(3.14) = 1.57 miles
d = rt
1.57 = 2a
.785 = a
Answer:
1.88 = ?
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent / hypotenuse
cos 20 = ?/ 2
Multiply each side by 2
2 cos 20 = ?
1.879385242 = ?
To the nearest hundredth
1.88 = ?
