Step-by-step explanation:
Using the Sine rule in Δ WXY
=
, substitute values
=
( cross- multiply )
x sin107° = 10 sin33° ( divide both sides by sin107° )
x =
≈ 5.7 ( to the nearest tenth )
Answer:

Step-by-step explanation:
we know that
The exponential function while the player is still active is equal to

where
y ----> is the value of the baseball card
x ----> the time in years
Find the value of y for x=7 years (7 years still active)

After 20 years
x=20-7=13 years (13 years retired player)
The initial value is 
The new equation is equal to

substitute
x=13 years
