Angles can be used to estimate the side lengths of a shape.
The letters in order of greatest to least are (a), (b) and (c)
The sum of angles at side (a) is:


The sum of angles at side (c) is:


The sum of angles at side (b) is:


So, we have:



The smaller the base angles, the longer the side.
Hence, the letters in order of greatest to least are (a), (b) and (c)

Answer:
y= 5 and -3
Step-by-step explanation:
subtract 7 from both sides to get y^2-2y-15=0
factor the equation to get (y-5)(y+3)=0
add five on both sides to get y=5 and subtract 3 on both sides to get y=-3
 
        
             
        
        
        
Answer:
The standard form is: 
The function is of the 3rd degree.
The leading coefficient is 8.
The constant term is -3.
Step-by-step explanation:
Placing in standard form:
To place in standard form, we solve the operations. So




Degree:
The degree is given by the highest power of x, which, in this exercise, is 3.
Leading coefficient:
The leading coefficient is the term that multiplies the highest power of x. In this exercise, the higher power of x is 
, which is multiplied by 8. So the leading coefficient is 8.
Constant term:
The constant term is the one which does not multiply a power of x. So in this exercise, it is -3.
 
        
             
        
        
        
Answer:
Let x be the number of tickets sold to adults and y the number sold to students:
x + y = 315. But we know that y was double x, then :
y = 2x
Plug the value of y (in the 1st equation) by 2x:
 x+ 2x = 315
3x = 315
and x = 105 (which is the number of tickets sold to adults
