Refer to figure 1 (see attached) for the initial drawing. The observation points are at A and B. I placed point A south of point B. The ship is at point C. I added in a compass as well.
As shown in figure 1, angle A is 33 degrees. You start by facing north and then you turn to face the eastward direction by 33 degrees. Angle B is 58 degrees. You start by facing south and then you turn 58 degrees to the east. The distance from A to B is 17 miles. Let's make c = 17. The lowercase c is opposite the upper case point C. Similarly, lowercase 'a' is opposite uppercase A; lowercase b is opposite uppercase B.
Once you have everything drawn out as shown in figure 1, we can use this info to find angle C
The three angles A,B,C add to 180 degrees
A+B+C = 180
33+58+C = 180
91+C = 180
91+C-91 = 180-91
C = 89
---------------------------------------------
Now use the law of sines to find the length of segment 'a'
a/sin(A) = c/sin(C)
a/sin(33) = 17/sin(89)
a = sin(33)*(17/sin(89))
a = 9.26027397983573
a = 9.3
Do the same for segment b
b/sin(B) = c/sin(C)
b/sin(58) = 17/sin(89)
b = sin(58)*(17/sin(89))
b = 14.419013720289
b = 14.4
---------------------------------------------
See figure 2 (attached) to see the fully solved triangle. When I refer to "solved triangle", I mean that we have found all of its sides and angles. In this case we have...
Angles:
A = 33 degrees
B = 58 degrees
C = 89 degrees
Sides:
a = 9.3 miles
b = 14.4 miles
c = 17 miles
Final answers are roughly 9.3 miles and 14.4 miles.
Answer:
c=a+b-180
Step-by-step explanation:
Since the equation is a+b-c=180, you subtract a and b from both sides, meaning it would be -c=-a-b+180, then you must multiply both sides by -1, and the answer would come out to c=a+b-180.
Either I've made a miscalculation... or none of these are correct...
1.7 in it's simplest form is 17/10.
So... neither A, B, C, or D is correct.
Answer:
94
Step-by-step explanation:
The triangle is split into two similar triangles. They have the same shape but not the same size. To solve, write a proportion to find KY.
Cross multiply to solve for KY.
95.2(KY) = 168(34)
95.2KY = 5,712
KY = 60
Add KY to 34 to find x.
60 + 34 = 94.
