Answer:
It is 6ft
Step-by-step explanation:
The formula is 
A= 1/2bh so now you would substitute
39= 1/2(13)h
78= 13h
6=h
 
 
        
             
        
        
        
Answer:
Part A: m+1.37=7.9
Part B: 6.53 miles are left to be repaired.
Step-by-step explanation:
Given,
Length of repaired part = 1.37 miles
Total length to be repaired = 7.9 miles
Miles left to be repaired = m
Part A:
Create an equation to show the relationship between the number of miles repaired and the number of miles left to be repaired, m.
Miles left to be repaired + Length of repaired part = Total length to be repaired
m+1.37=7.9
Part B
How many miles are left to be repaired?
Subtracting 1.37 from both sides
6.53 miles are left to be repaired.

I'd like to assume that the triangle is a right triangle and you solve for x so...
133 + c = 180   (supplementary property to find one angle of triangle)
          c = 47
x = 180 - 90 - 47 (int. angles of triangle = 180)
   = 90 - 47
   = 43
Therefore, x is 43 degrees
        
             
        
        
        
we can use formula 

we can compare 
we get 
a=x
b=2
now, we can plug that in formula 
and we get 

now, we can simplify it
