Answer:
d = 2.2
Step-by-step explanation:
Using the distance formula, you would plug in the numbers into the equation. d = √(5 - 3)^2 + ( -3 + 2)^2. So (5 - 3) is 2, and (-3 + 2) is -1. Then square both of the answers, and the equation becomes, d = √4 + 1. And that equals 5, so then you would find the square root, which would be approximately 2.2
So to find the answer to this, you have to consider that

- half because half the pocket money (x) was spend on clothes, then plus 9 because that's how much extra she gained and 13 because that was the result of all the changes.
To solve this, first subtract 9 from both side, which leaves you with

and

is the same as

, so to solve this, multiply both sides of the equation by two, resulting in

. SO from this we can conclude that the weekly allowance is $8
answer. X=50
as..
draw a imaginary line between M
let it one side be y and z
y+z=120
now,
y=70(being alternate angle)
y+z =120
so
z=120-70
z=50
as we know,
z is alternate to X
so ,X=50
The area of a sector is 339.336 cm²
The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.
It can be determined by using the formula:

Given that;
- Radius r = 18 cm
- Angle θ = 120°
Then. the area of the sector can be calculated as:


A = 339.336 cm²
