Cos = adjacent / hypotenuse
cos 25° = 4 / AB
cos 25° • AB = 4 / AB • AB
AB cos 25° ÷ cos 25° = 4 ÷ cos 25°
AB = 4/cos 25°
AB = 4.41 (nearest hundredth)

Whats the problem so i can solve for the whole in tire problem
Answer:
Step-by-step explanation:
y = -x - 1
the slope here is -1. A parallel line will have the same slope
y = mx + b
slope(m) = -1
(5,-5)....x = 5 and y = -5
now we sub....we are looking for b, the y int
-5 = -1(5) + b
-5 = -5 + b
-5 + 5 = b
0 = b
so ur equation is : y = -x + 0....or just y = -x
