Answer:
The total distance Remy will swim is approximately 236 meters
Step-by-step explanation:
From the given diagram, of triangle ΔCAB, we have that the path Remy is to swim are;
1) Length of segment C to A
2) Length of segment A to B
3) Length of segment B to C
The length of the perpendicular at point D on segment AB to C = 60 meters
Therefore, DC = 60 m
By trigonometric ratios, we have;


We are given the values of the trigonometric ratios of the following angles;
tan(27°) = 0.51
tan(43°) = 0.93
cos(27°) = 0.89
cos(43°) = 0.73
∴ tan(43°) = AD/DC = 0.93
Where the lengths of AC, AD, DB, DC and BC
AD = DC × tan(43°)
∴ AD = 60 × 0.93 ≈ 55.8
Similarly, we have;
tan(27°) = DB/DC
∴ DB = DC × tan(27°)
DB = 60 × 0.51 ≈ 30.6
From
, we have;
cos(43°) = DC/AC
AC = DC/(cos(43°))
∴ AC = 60/0.73 ≈ 82.2
Similarly, we have;
cos(27°) = DC/BC
BC = DC/(cos(27°))
∴ BC = 60/0.89 ≈ 67.4
The total distance Remy will swim = AC + AD + DB + BC
∴ The total distance Remy will swim = 82.2 + 55.8 + 30.6 + 67.4 = 236
The total distance Remy will swim = 236 meters
Using the order of operations (PEMDAS)...
23 · 1 - 1 = ?
23 - 1 = ?
22
The answer is 22

Answer:
k = 102
Step-by-step explanation:
Inverse variation is represented as follows:
y = k/x
Find k by substituting 17 for y and 6 for x:
17 = k/6
Multiplying both sides by 6 results in k = 102
Answer:
You use the facts about a 30, 60, 90 triangle.
Step-by-step explanation:
The angles in a triangle add up to 180.
90+30+x=180
120+x=180
x=60
This is a 30-60-90 right triangle.
The side opposite the 30 degree angle is a.
The side opposite the 90 degree angle (hypotenuse) is 2a.
The side opposite the 60 degree angle is a
We know the side opposite the 90 degree angle.
2a = 12
Divide by 2.
a=6
a is the side opposite the 30 degree angle (y)
Because we know a, we can find a
.
6
The square roots cancel, leaving 3.
6 times 3 is 18.
Therefore, the side opposite the 60 degree angle (x) is 18.
Long sleeves hope this helps
