Left 4. Or x-4 because the way it moves
Answer:
47.45754235
31.46697634
Hey do you need to show your work for these? I found an answer key
Step-by-step explanation:
We need to use law of cosines
c²=a²+b²-2abcos(C)
let x= angle xzy
plugging in what we have the equation looks like
17²=22²+20²-2*22*20*cos(x)
289=484+400-880cos(x)
.676136364=cos(x)
x=47.45754235
b.)
The smallest angle should be opposite to the smallest side
Using the law of cosines again we get
9²=13²+17²-2*13*17*cos(x)
81=458-442cos(x)
.852941176=cos(x)
x=31.46697634
Let's find the value of x :
According to given picture, the angles (x + 75)° and (x + 125)° forms Co interior angle pair.
so,
hence, value of x = -10°
80•5nights is 400
25% of 400 is 100
400-100 discount is 300
20% of 300 is 60
300+60 is 360
Answer:
The answer to your question is the letter B. 3,037
Step-by-step explanation:
Data
b = 600
B = 11°
C = 75°
c = ?
Process
1.- To solve this problem, use the law of sines
b/sin B = c/sin C
2.- Solve for c
c = b sin C / sin B
3.- Substitution
c = 600 sin 75 / sin 11
4.- Simplification
c = 600 (0.966) / 0.191
c = 579.55 / 0.191
5.- Result
c = 3037
