You factor out primes from the root, for example:
root 100
you can get 10 from it, or we'll use 5
100/5=20
20/5=4
root 4= 2
because there are 2 "5" we can bring that out of the root, there are 2 "2" so we bring that out too.
When a number is taking out of a root, the 2 exact same numbers become one. in this case, there are ONE 5 and ONE 2 outside the root. then You multiply 5 and 2 together, and you get 10
Based off of what I can see in the photo (its too blurry to know for sure) and what I think you're asking:
The angle of a triangle always adds up to 360degrees, so base it on that and the acute and obtuse angles and get the degrees from there, the angle would be those degrees you find or <10, 5, 4 (what I assume is a 5)
Answer:
lamar served 40
kira served 20
david served
i just spent like 15 minutes trying to figure this out and when i finally got it i was so mad because it was such a simple error i was making
Step-by-step explanation:
Perimeter = 4×
Where x = 5/7
4* 5/7
p= 20/7
The answer will be a mixed fraction
p= 2 6/7 units
Hope that helps!
