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
Answer:
B
Step-by-step explanation:
When finding the area of a circle you have to use the formula
Area= Pie x radius^2
Radius=8.5
So you have to plug that into the equation.
8.5x8.5=72.25
72.25x3.14=226.87
So Area is 226.87
So your answer is B
Answer:
4. 52 ft^2
5. 25 ft^2
Step-by-step explanation:
15 -11 To get the width of scrapbooking which is = 4
4 * 13 = 52 ft^2
9 - 4 = 5 ft
5 * 5 = 25ft
