Answer:
A. 58.04°
Step-by-step explanation:
Let the sides of the triangle be A , B and C.
A = 32
B = 35
C = what we don't know.
The opposite angle to C is 120° and its just denoted as ∡C
The formula to find C² = A² + B² - 2ABcos∡C
C² = 32² + 35² - 2(32)(35)cos120°
C² = 1024 + 1225 - 2240cos120°
C² = 3369
C = 
≅ 58.04°
Answer:
2
Step-by-step explanation:
common sense
Let x be the number of minutes Jim used
105.60 = 75+0.30(x−1000)
105.60=75+0.30x−300
105.60=0.30x−225
1056=3x−2250
1056+2250=3x
3306=3x
x=1102
Answer:
Let X be the number of weeks.
2x - 16 = 14
we add 16 on both sides.
2x = 30
now we divide 2 on both sides to get rid of the 2 to the x, we want to get x on its own.
X = 15
