For this case we have a triangle, in which we are given two angles and we must find the missing angle. We know that by definition, the sum of the internal angles of a triangle is 180 degrees.
Where "y" represents the measure of the missing angle.
Clearing "y" we have:
Thus, the missing angle isdegrees.
Answer:
degrees

In triangle OPQ, o = 700 cm, p = 840 cm and q=620 cm.
To find:
The measure of angle P.
Solution:
According to the Law of Cosines:
Using Law of Cosines in triangle OPQ, we get
On further simplification, we get
Therefore, the measure of angle P is 79 degrees.
