Answer:

Step-by-step explanation:
In order to find the side mentioned (IJ), we need to use SOH CAH TOA. 
SOH CAH TOA is an acronym to help us remember what sin, cos, and tan mean. It stands for:
Sin = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tan = Opposite / Adjacent
Since we know the measure of angle K (42) and we know one of the sides, we can use this to find the missing length.
Since the side given to us is the hypotenuse, and we're looking for the side opposite of the angle (IJ), the only possible one to use would be SIN as it includes Opposite and Hypotenuse.
Our equation is now this: 
Let's now solve for x.
Therefore, the length of IJ will be around 2.01.
Hope this helped!
 
        
             
        
        
        
Answer:
Pattern: subtract 2 from the input to get the output
When the input is 9, the output is 7
When the input is 13, the output is 11
Step-by-step explanation:
» <u>Application + Solution</u>
 To find the pattern, we have to look for common things we notice between the input and output.
- After analyzing, we can surely notice that we subtract two from the input each time to get the output because 3 - 2 = 1, 8 - 2 = 6, 15 - 2 = 13, and 20 - 2 = 18.
 Now that we realized the pattern, we subtract 2 from 9 and 13.
 
        
             
        
        
        
Area of a rectangle = Length x Breadth
The required area = 500 x 300
 = 150000 m^2

Step-by-step explanation:
Let her brother's age be x
Sarah is 2x + 4
 
        
             
        
        
        
It would be equal to 110 2/7
