Answer:
4.42
Step-by-step explanation:
Data obtained from the question include the following:
Angle θ = 70°
Hypothenus = AB = 13
Adjacent = BC =?
Sin 70° ≈ 0.94
Cos 70° ≈ 0.34
Tan 70° ≈ 2.75
Next, we shall determine the measurement of BC as follow:
Since we are to obtain the adjacent, we shall use the following equation:
Cos θ = Adjacent /Hypothenus
Cos 70° = BC /13
0.34 = BC /13
Cross multiply
BC = 0.34 x 13
BC = 4.42
Therefore, the measurement of BC is 4.42

Answer:
105 balcony tickets
Step-by-step explanation:
c = orchestra seats, b = balcony seats
c + b = 360
45c + 35b = 15150
You can solve by substitution or elimination.
c = 255
b = 105
