Answer: 33.85 mm
Step-by-step explanation:
Use trigonometry, tan equation 
You are give the tan angle and adjacent side, you need to find the opposite side so
 O
T A
Tan(72)= x/11
x= tan(72) x 11
x= 33.85
 
        
                    
             
        
        
        
Answer:
C
Step-by-step explanation:
a (5) = c (4)
5 x 4 = 20 
20 (total) divided by the 5 apples is $4.
 
        
                    
             
        
        
        
If you graph out y = x^2 - 1, you'll see that it is a curved parabola. It is not a straight line. So visually this shows the equation is not linear. It's considered nonlinear.
Algebraically, the given equation does not fit the form y = mx+b which is slope intercept form. So this is more confirmation that we do not have a linear function.
        
             
        
        
        
Actually, this is not about angles.  It's about the length of the sides in a right triangle.
In EVERY right triangle, the squares of the lengths of the short sides add up 
to the square of the length of the longest side.  You're in high school math,so 
I'm SURE you've heard that in class before ... possibly even just before you 
were assigned this problem.
Let's say that again:  The squares of the lengths of the sides that meet at 
the  right angle add up to the square of the length of the longest side.  In 
the triangle in this particular problem, that means 
                                                                             a² + b² = c²
You know the lengths of 'b' and 'c', so you shouldn't have any trouble finding 
the length of 'a'.
