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
Answer:
650=65% of 1000
Step-by-step explanation:
650-600=65 or 65%
Answer:
I don't know 1
2. 3/4
3. y= 1000(0.75)^x
Step-by-step explanation:
If it's just distribution, not solving for s (I mean I could but do you need to?):
5(2s² - 3s + 4) Distribute/multiply 5 into (2s² - 3s + 4)
(5)2s² - (5)3s + (5)4
10s² - 15s + 20
Answer:
90 degree angle.
Step-by-step explanation:
Right triangles must have a 90 degree angle or it is not a right triangle.
