I need help figuring out this problem. My teacher tried explaining but i just got more confused.

One end of a wire is attached to the top of the tower and the other end to a stake in the ground that is 44’ from the base of the tower. The wire makes a 64 degree angle with the flat ground. If she...

explain when one should use the law of cosine instead of the law of sine

Explain when the law of sines will give you a unique solution

Matt measures the angle of elevation of the peak of a mountain as 35 degrees. Susie, who is 122 feet closer on a straight level path, measures the angle of elevation as 42 degrees.

Base = 29cm, height = 8 cm, angle between the two = 100 degrees.

Tami and Dustin are on opposite sides of the washington monument, which is 555 feet. Tami's angle of elevation to the top of the monument is 38 degrees. Dustin's angle of elevation is 64 degrees....

An air traffic controller is tracking a plane 3.4 miles due north of the radar tower. A second plane is located 2.1 miles from the tower at a heading of 72 degrees north of west. To the nearest tenth...

For the triangle ABC, which of these is not a Law of Cosines? (a) a2=b2+c2-2bc cos A (b) b2=c2+a2- 2ac cos B (c) c2=a2+b2-2ab cos C (d)...

Given the triangle ABC with angles A= 58°, B=70°, and side c=21cm. Using the Law of Sines, find the length of the side a. Approximate your answer to the nearest whole number. Show all...

A port and a radar station are 5 mi apart on a straight shore running east and west. A ship leaves the port at noon traveling at a rate of 19 ?mi/hr. If the ship maintains its speed and? course, what...

Find the value of side b for each triangle using The Law of Sines: 1)A=24.3 degrees C=54.6 degrees a=2.68 2)B=10 degrees C=135 degrees c=45 3)A=10 degrees B=60 degrees a=7.5...

1)The bearing from A to B is 40°. Determine the bearing of A from B. 2) If the beating from A to B is 120 degrees. Determine the bearing of A from B. 3) Describe in words what the bearing...

P.s sorry can't draw the triangle it would have made it easier. AB is 211. BC is 142. AC is 185. Thanks :)
