Answer:
Step-by-step explanation:
SOH CAH TOA can remind you of the relationships between triangle measures. The distance east is the side of the right triangle that is opposite the angle, so is related to the hypotenuse (ship's travel distance) by the sine function.
sin(43°) = (travel distance)/(distance east)
So, ...
(distance east) = (travel distance)·sin(43°)
Likewise, the cosine function can be used to find the distance south.
Then we have ...
east = (130 km)sin(43°) ≈ 95 km
south = (130 km)cos(43°) ≈ 89 km
Answer:
216
Step-by-step explanation:
First find the base area
0.25 * √[(5 + 6 + 5) * (-5 + 6 + 5) * (5 - 6 + 5) * (5 + 6 - 5)] = 12
Equation:
12 * (5 + 6 + 5) + (2 * 12) = 216
Answer:
$4.86
Step-by-step explanation:
2.97/11 =.27 .27 x 18= 4.86
9/12 in simplest form would be 3/4 because you divide bothe 9 and 12 dived by three because what you do to the denominator you do to the nominator so after you divide 9/12 by 3 you would have 3/4 which 3/4 is 9/12 in simplest form
