Answer:
49°
Step-by-step explanation:
7.5x-15+90=180 
 7.5x+75 =180 
 7.5x=105
x =14 
so NPQ = ( 4×14 -7 ) = 49° this the answer

The value of 18x + 9∆x - 7 based on the limit given will be 18x - 7.
<h3>How to calculate the value?</h3>
From the information given, it should be noted that we simply want to calculate the value of x. 
This will be:
18x + 9∆x - 7
It was stated that ∆x = 0
Therefore, we'll put this into the equation.
This will be:
18x + 9∆x - 7
= 18x + 9(0) - 7
= 18x -7
