Answer:
The answer to your question is: ∠K   = 138°
Step-by-step explanation:
m∠N = 42° 
m∠K = ?
The sum of all the internal angles in a quadrangle equals 360°
then
         ∠N + ∠L + ∠M + ∠K = 360°
         ∠N = ∠ L   and ∠M = ∠K
So, 2 ∠N + 2 ∠K = 360
Substitution 
        2 (42) + 2 ∠K = 360
        84  + 2 ∠K = 360
        2 ∠K = 360 - 84
        2 ∠K = 276
       ∠K  = 276 / 2
      ∠K   = 138°

Answer:
0.00310 miles
Step-by-step explanation:
Maria runs 5 m each week. We need to find how miles she run. It means we need to convert meters to miles. The relation between meter and yards is as follows :
1 meter = 1.09361 yards
Also, 1 mile = 1760 yards
It means, 
1 mile = 1609.34 m
1 m = (1/1609.34) miles

So, she will cover 0.00310 miles.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
We are given the Inequality:

First, we can simplify the expression. On the left side of Inequality, we can cancel 2; on the right side, we can cancel 2 out as well.
Simply, division!

2 divides 2 is 1; 2 divides 10 is 5.

Generally, it is not recommended to write 1 beside the variable nor write 1 as a denominator.
Simplify the expression:-

Therefore, the value of y is less than 5.

Answer:
-1/36
Step-by-step explanation:
-5/18  - ( -1/4)
Subtracting a negative is like adding
-5/18 + 1/4
Getting a common denominator of 36
-5/18 *2/2 + 1/4 *9/9
-10/36 + 9/36
-1/36
