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
Let
x----------------- > <span>the height of the smaller painting
y-----------------> </span>the height of the tall painting-----------> 6 ft<span>
the scale factor is-------------- > x/y
(x/y)=(4 in)/(1.5 ft)
x=y*[</span>(4 in)/(1.5 ft)]-------> 6*(4 in)/(1.5 ft)=16 in
<span>
the answer is x=16 in
</span>
Answer: $2
Step-by-step explanation: 20 percent of 10 is 2
Hope I did this right
113.04 divided by 3.14 is 36 so <u>36</u> <u>is the</u> <u>diameter and to find the radius you just divide 36 by 2 and that is 18.</u>
