Answer:
or 
.
Step-by-step explanation:
Suppose, the first side is a, the second side is b, and the third side is c. So:
→ a = s - 4
→ b = s
→ c = (s - 4) + 3
→ a + b + c = 15
First step, find the value of s
a + b + c = 15
(s - 4) + s + (s - 4) + 3 = 15
3s - 5 = 15
3s = 15 + 5
3s = 20
So, the third side is
c = (s - 3) + 4
c = s + 1
c = 
.
Happy to help :)
There’s an app that can solve this easily called photo math it’s what I used But x= 3
Answer:
√32 or partially rooted 4√2
Step-by-step explanation:
defined as..
√((x2-x1)²+(y2-y1)²)= distance between 2 points
√((5-1)²+(7-3)²)= √32
Answer:
24
Step-by-step explanation:
the denominator is the number that is down or under the fraction line
First box is EF.
Second box is segment congruence postulate.
Third box is segment additon postulate.
Fourth box is DF. For this one the last sentence basically gives you the answer.
Just so you know for the fourth I guessed on if it's DF lined or DF unlined. I made my educated guess on the fact that the last line doesn't have a line. I hope this helps, and please tell me if I got something wrong, or my explanation wasn't sufficent enough for you.
