Answer to Problem 3E
When solving an oblique triangle given two sides and their included angle, use the standard form of the
Law of Cosines to solve for remaining side.
Explanation of Solution
Given information:
When solving an oblique triangle given two sides and their included angle, use the
Law of Cosines to solve for remaining side.
Calculation:
Let ABC is an oblique triangle,
So, the standard form of the Law of cosine is
Let sides are
Substitute these values in the Law of cosine formula,
Take square root on both sides.
So, the missing side is
So, when solving an oblique triangle given two sides and their included angle, use the standard form of the
Law of Cosines to solve for remaining side.
