We can solve for side AB using the trigonometric ratio cos, where cosA=adjacent/hypotenuse.

$cos25= \frac{7}{x} = x= \frac{7}{cos25} =$ 7.7

Cos = adj/hyp

steposvetlana [31]

Answer:

$90.00

Step-by-step explanation:

Given

$c = 45.00$ --- base fee

$m = 15.00$ --- rate

$x = 3$ --- individuals

Required

Determine the total amount paid (y)

The relationship between the variables is:

$Total = Base\ Fee + Rate * Individuals$

$y = c + mx$

This gives:

$y = 45.00 + 15.00 * 3$

$y = 45.00 + 45.00$

$y = 90.00$

Hence, the amount is $90.00
