Answer
62
5.3
65
5.8
2.5
Step-by-step explanation:
FOr the first one we have the opposite and adjacent side, so we'll use TOA
let x= angle
tan(x)=4.7/2.5
x=61.99 or 62
2.) for this one we can just use pathagoryeous thereom
2.5²+4.7²=c²
28.34=c²
c=5.323
3.) For this one we know that the angles in a traingle must add to 180
let x= missing angle
25+90+x=180
x=65
4.) For this one we have the adjacent side but need the hypotonouse
we will therefore use CAH
cos(25)=5.3/x
5.3/(cos(25))=x
x=5.8
5.) For this one we will just use the pathagoryeous to solve for the missing side
a²+5.3²=5.8²
a²=6.107
a=2.5
Hey there! :)
(-5 - x)/(3) < 4
Start out by multiplying both sides by 3. This is to get rid of any fractions we have!
3 • (-5 - x)/(3) < 4 • 3
Simplify!
-5 -x < 12
Add 5 to both sides so that we can isolate our variable.
-5 - x + 5 < 12 + 5
Simplify!
-x < 17
Divide both sides by -1.
Keep in mind that when dividing by a negative number, you must change the sign of the “crocodile mouth.” So, < turns into >.
-1 / -x > 17 / -1
Simplify.
x > -17
Hope this helped! :)

Answer:
45%
Step-by-step explanation:
Simply divide your partial amount (18 in this case) by your total (40), and you then multiply your answer from 18/40= .45 by 100, and you get 45. This is 45%
