You look at the triangle...
The sides there are four
The base is the bottom
...
9900 because you divide 99000 by 10
Answer:
Step-by-step explanation:
Using the cosine theorem:



The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees
x = 2(180 - x) - 12
3x = 348
x = 116
The measure of the angle is 116 degrees.
Answer:
-1/6
Step-by-step explanation:
5a+2/3=-1/6
5a=-1/6-2/3
5a=-1/6-4/6
5a=-5/6
a=(-5/6)/5
a=(-5/6)(1/5)
a=-5/30
simplify
a=-1/6
