Step-by-step explanation:
DEFINITION: Besting: the clockwise totation (0° to 360°) from North to any line.
A) Calculate the bearings of D from A:
bearings of D from A =x
looking the picture:
x=48°+55°+180°
x+103°+180°
x=283°
B)Calculate the bearings of A from C:
bearings of A from C =y
180°+55°=y
y=235°
C) Calculate the distance between A and B:
The angle in B is 74° (Because 55°+51°+74°=180°)
Using the Law of sines:

D)Calculate the distance between D and C:
Using the Law of cossines:

E) A Helicopter is hovering at A at a height of 2.5Km, find angle of elevation of helicopter from C:
The triangle HBA is rectangle

α=7,49°
X=2 y= 12+6x, xeR

Answer:
7 games
Step-by-step explanation:
Ricardo has 2 cases with x number of games in each. This means 2x is the amount of video games in both. He gives away 4. He now has 2x-4 and has 10 left. This is 2x-4=10. Solve for x.
2x - 4 = 10
2x = 14
x=7
A) QPT=34 opposite interior with PRS
b)SPT=146-34=112
c)TSR+SRT+RTS=180
TSR+34+(180-46)=180
TSR+34-46=0, TSR=12
d)QRS=146
e)PQR+QPS=180
PQR+146=180
PQR=180-146=34
The answer is $6.50 hope this helped
