Multiply both 3 and 7 by 2, this gives you equivalent fractions (there are more possible equivalent equations of course)
There is a not so well-known theorem that solves this problem.
The theorem is stated as follows:
"Each angle bisector of a triangle divides the opposite side into segments proportional in length to the adjacent sides" (Coxeter & Greitzer)
This means that for a triangle ABC, where angle A has a bisector AD such that D is on the side BC, then
BD/DC=AB/AC
Here either
BD/DC=6/5=AB/AC, where AB=6.9,
then we solve for AC=AB*5/6=5.75,
or
BD/DC=6/5=AB/AC, where AC=6.9,
then we solve for AB=AC*6/5=8.28
Hence, the longest and shortest possible lengths of the third side are
8.28 and 5.75 units respectively.
Answer:
Nah, I don't think so. But if that real, then woah
Step-by-step explanation:
<5, 2> - <2, -3> = <5 - 2, 2 - (-3)> = <3, 5>
Answer:
Janie is 12
Chad is 15
Step-by-step explanation:
27 - 3 = 24
24 : 2 = 12
12 + 3 = 15 (Chad)
27 - 15 = 12 (Janie)
