You begin by finding the measure of the angles knowing that all angles in a triangle equal 180.  Then you use tan 57=7/(line AC).  This value squared plus 7 squared will equal the length of the hypotenuse squared.

A technician charges P 400 per hour and spends P 500 a day on gasoline. Write an alcat expression to represent his earnings for
Basile [38]

Answer:

y=400*x-500

Step-by-step explanation:

The expression that represents the problem is:

y=400*x-500

Function y represents earnings for one day.

400 is the fixed number that is charge for one hour work

x represents the number of hours that the technician has worked for one day

To find the total earnings you should multiply the fixed charge for one hour work (400) by the number of hours worked in a day.

Then you need to substract the cost of gasoline in a day, it is 500 and it is a constant in the equation since it doesn't depend on the number of hours worked.

So, the function is:

y=400*x-500
