Step-by-step explanation:
no because it is not a right angled triangle.
this means angle A is not 90° so AB cant be a tangent.
<span>(2) y is the total cost, x is the number of months of service, $40 is the installation fee, and $90 is the service charge per month.</span>
y = 40 + 90x
y = total cost
x = number of months of service
40 = one time installation fee
90 = monthly service charge.
Let us assume that the number of months of service is 10 months. then, the total cost would be:
y = 40 + 90(10)
y = 40 + 900
y = 940
This is not true.
where is 
is any integer. So suppose we pick some value of 
other than these, say 
. Then
