Help with this question please​
Allisa [31]

Step-by-step explanation:

The LKM angle is an enclosed angle. So its size is half the arc facing it.

LKM (angle) = ½ LM (arc)

The LMN angle is a shadow angle. So its size is half the size of the arc facing it.

LMN(angle) = ½ LM(arc)

so:

LKM = LMN

A girl scout troop sold cookies. If the girls sold 5 more boxes the second week than they did the first, and if they doubled the
VARVARA [1.3K]
N = first integer 
n + 1 = second integer 
n + 2 = third 
n + 3 = fourth 

the sum is 114 so: 

n + (n + 1) + (n + 2) + (n + 3) = 114 

solve: 

4n + 6 = 114 
4n = 108 
n = 27 

so 27 is your first. 
27 + 1 is your second (remember n +1 n +2 and n +3) 

so your first four integers are: 27 28 29 and 30 


(I'll also help with one) 

week one: x 
week two: x + 5 
week three: 2(x+5) or 2x + 10 

week1 + 2 + 3 = 431 

so its: 

x + (x+5) + (2x + 10) 
4x + 15 = 431 
4x = 416 
x = 104 

its then: 

week one: 104 sold 
week two: 109 sold (x + 5) 
<span>week three: 218 (2x + 10)
