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.

Step-by-step explanation:
x²-3x +5x -15=33
x²-3x+5x=33+15
x²-3x+5x=48
x²+2x=48
divide both sides by 2
x²+x =24
x²= 24
x= ✓24

Answer:
Angles and XWY and STR 
Step-by-step explanation:
These two angels are alternate exterior angels because: 
- They are on different sides of the transversal (the line intersecting the two parallel lines) 
- They have the same angle measure
- They are exterior, meaning they are on the outside, not inside (interior)
Hope this helps!!! :)
