Given:
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.
Answer:
from the picture the answer is D.
Step-by-step explanation:

to find x subtract 18x from 4x which will give you -14x=-36
divide both sides by -14
4.41 ounces. 1.5 +2.25 + .66=4.41. You just multiply the faction by the number and add it all up.

a point (x, y ) → (y, - x ), thus
(- 3, - 6 ) → (- 6, 3 )
