Answer:
The distance from Gary's school to the BART station is 564 yards
Step-by-step explanation:
Let
x ----> the distance from Gary's school to the corner market
y ----> the distance from Gary's school to the BART station
we have
we know that
To find out the distance from Gary's school to the BART station, multiply the distance from Gary's school to the corner market by 12
so
substitute the value of x
therefore
The distance from Gary's school to the BART station is 564 yards

Answer:
The approximated length of EF is 2.2 units ⇒ A
Step-by-step explanation:
<em>The tangent ratio in the right triangle is the ratio between the opposite side to the adjacent side of one of the acute angle in the triangle</em>
In the given figure
∵ The triangle DFE has a right angle F
∵ The opposite side to angle D is EF
∵ The adjacent side to angle D is DF
→ By using the tangent ratio above
∴ tan(∠D) =
∵ DF = 6 units
∵ m∠D = 20°
→ Substitute then in the ratio above
∴ tan(20°) =
→ Multiply both sides by 6
∴ 6 tan(20°) = EF
∴ 2.183821406 = EF
→ Approximate it to the nearest tenth
∴ 2.2 = EF
∴ The approximated length of EF is 2.2 units
