Use law of cosines
o^2=p^2+q^2-2pqCos(C)
o^2=38^2+29^2-38*29Cos(39)
o^2=1444+841-1712.83
o^2=572.17
o=23.92
Say 24 cm
Answer: $82,000
Step-by-step explanation:

{ 5 x - y = 20
2 x + y = 15
_____________
7 x = 35
x = 35 / 7
x = 5
For y :
2 x + y = 15
2*(5) + y = 15
10 + y = 15
y = 15 - 10
y = 5
Answer A ( 5,5 )
