A straight line is 180°. 180°-135°=55°, so x=55°, which is an acute angle because it is less than 90°.
 
        
                    
             
        
        
        
Answer:
The temperature in Kelvin corresponding to F degrees Fahrenheit is 
Step-by-step explanation:
Given : One can convert temperature from Kelvin into Fahrenheit using the formula  .
. 
To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?
Solution : 
Temperature from Kelvin into Fahrenheit is given by,

Writing Kelvin in terms of Fahrenheit,
Subtract 32 both side,

Divide by 95 both side,

Add 273 both side,

Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is 
 
        
                    
             
        
        
        
Answer:
4
Step-by-step explanation:
firstly you separate y 
y=-x-1
 which means that the slope is equal to -1
then you flip the slope so -1 over -1 which is equal 1
 
        
             
        
        
        
For the first question, it would be D: 

 ÷ 9. This is because to solve a division problem with fractions, you would need to multiply the first fraction by the reciprocal of the second fraction. For the second question, the answer would be D: 32. This can be solved by dividing 8 by 

 or 0.25. For the third question, it would be D. 

. This can be solved by dividing 

 by 3. For the fourth question, the answer would be 

. This can be found by flipping the 4, which would make it look like 

, and multiplying it by 

. For the last question, 1 would be B, 2 would be C, 3 would be C, and 4 would be A.
Hope this helps ^-^
