Answer:
Step-by-step explanation:
4). By applying cosine rule for angle R,
cos(∠R) = 
cos(33°) =
[Equation]
x = 19cos(33°)
= 8.39
5). By applying sine rule,
cos(20°) = 
cos(20°) =
[Equation]
x = 
x = 15.96
6). By applying tangent rule,
tan(40°) = 
tan(40°) =
[Equation]
x = 
x = 17.88
R = 14.1
Explanation:
r - 17.3 = -3.2
r = - 3.2 + 17.3
r = 14.1
Answer:
4 pi
Explanation: for one whole cycle it’s 4 pi
To get this answer you set up an equation. 0.95x=57. You then divide both sides by 0.95 giving x=57/0.95 which equals x=60. Therefore, the what number is 60 because 60*0.95=57.
