Write down your strategy for solving an oblique triangle.
Answer to Problem 62AYU
The Law of sines is used to solve case 1 and case 2 while the Law of Cosines are used to solve case 3 and case 4.
Explanation of Solution
Given information:
Write down your strategy for solving an oblique triangle.
Calculation:
To solve an oblique triangle means to find the lengths of its sides and the measurements of its angles, we need to know the length of one side along with
Two angles
One angle and one other side; or
The other two sides
There are four possibilities to consider.
One side and two angles are know (ASA or SAA).
Two sides and the angle opposite one of them are known (SSA).
Two sides and the included angle are known (SAS).
Three sides are known (SSS).
Hence, the Law of sines is used to solve case 1 and case 2 while the Law of Cosines are used to solve case 3 and case 4.
