Answer:
X=3252
Step-by-step explanation:
Your formula is $49645+$12.25x=$15499+$22.75x
X represents the number of books sold.
$49645+($12.25*3525)=$39,837
$15499+($22.75*3252)=$39,837
Trigonometry:
Sine 75 = x/ 9
x = 9 Sine 75
x = 8.7
Answer:
22.77°
Step-by-step explanation:
Using SOH CAH TOA trigonometry identity
Height of the building (opposite side) = 172ft
Length of the shadow (hypotenuse) = 444ft
Using SOH
sin theta = opp/hyp
Sin theta = 172/444
Sin theta = 0.387
theta = arcsin0.387
theta = 22.77°
Hence the angle of depression is 22.77°
