Answer: If the point of the circle P has coordinates: P=(x,y)
sine (Angle) = y/r
cosine (Angle) = x/r
tangent (Angle) = y/xw
where r=sqrt(x^2+y^2) is the radius of the circle
Example:
P=(3,4)=(x,y); x=3 and y=4
Radius of the circle: r
r=sqrt(x^2+y^2)
r=sqrt(3^2+4^2)
r=sqrt(9+16)
r=sqrt(25)
r=5
sin(Angle)=y/r
sin(Angle)=4/5
cosine(Angle)=x/r
cosine(Angle)=3/5
tangent(Angle)=y/x
tangle(Angle)=4/3
An outside angle is equal to the sum of the two opposite inside angles.
The triangle has an outside angle of 98, it's two opposite inside angles are given as 32 and X.
To find X, subtract 32 from 98.
X = 98 - 32 = 66
The answer is B.
Answer:
- <u>Faisal will receive $ 241</u>
- <u>Ahmed will receive $ 482</u>
- <u>Walid will receive $ 723. </u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Profit Ahmed, Walid and Faisal made from selling used books = $ 1,446
Ahmed to receive double amount of Faisal
Walid to receive triple amount of Faisal
2. How much does each one receive?
- Let x to represent the amount Faisal to receive
- Let 2x to represent the amount Ahmed to receive (double amount of Faisal)
- Let 3x to represent the amount Walid to receive (triple amount of Faisal)
Therefore, we have:
x + 2x + 3x = 1,446
6x = 1,446
x = 1,446/6
x = 241 ⇒ 2x = 482 ⇒ 3x = 723
<u>Faisal will receive $ 241, Ahmed will receive $ 482, and Walid will receive $ 723. </u>
Hi
Use Euler's formula for this for a 3D figure. F + V = E + 2, where F is the number of faces, V is the number of vertices, E is the number of edges, +2! You have enough info to fill in the formula to find that the number of vertices is 6.

The answer Is 2/12 because if u multiply 1 x2 it is 2 then 3 x4 which is 12
