(1,3). Is an ordered pair that is a solution.
Or
(2,-3)
From the given problem, I gather that there are only two groups of forces. These are:
13 lb, 35 lb, resultant force 30 lb
20 lb, 15 lb, resultant force 25 lb
We use the pythagorean theorem to determine if the three forces are grouped correctly, such that the resultant force is the hypotenuse.
Resultant Force = √(a² + b²)
So, for the first group,
30 ? √(13² + 35²)
30 ≠ 37.33
Thus, the first group does not pull at right angles to each other.
For the second group,
25 ? √(20² + 15²)
25 = 25
Thus, the second group does pull at right angles to each other.
Answer:
Segment GD is half the length of segment HC.
Step-by-step explanation:
If Lea was given 23 surveys at school and she needs to have twice that amount then you just multiply 23 by 2 and get 46 surveys by the end of the week. Lea is probably pretty tired after that haha
Shouldnt it equal 180°? That would make the answer 80 right??
