The pelican is 16 feet ABOVE the water, then dives 20 feet to get to the fish. Basically, just do 20 minus 16, which would be 4 feet. So the pelican is 4 feet below sea level.
Answer:
c =38
Step-by-step explanation:
<71 has an arc of 2 * 71 =142
The arc 104+ c
142 = 104+c
142-104 =c
c =38
It would be 33.5, because 1/2 as a decimal is .5
The question was incomplete. Below you will find the missing image.
Only the Saki's triangle can be solved using law of cosines.
Law of cosines formula is used to find missing including angle or missing side.
It is used in SAS and SSS triangles.
If a, b & c are three sides and C be the vertices opposite to side c then,
c²=a²+b²-2ab×CosC
Here in the given image we see that,
In Anna's triangle, there is one side and one angle.
So, it is not possible to solve with law of cosines.
In Yuna's triangle, there are two angles and one side.
So, also it is not possible to solve with law of cosines.
In Carley's triangle, there are three angles.
Also in this case, law of cosines it not possible to use.
In Saki's triangle, there are three sides are given. So, it is a SSS triangle.
We can apply the law of cosines here in this triangle.
