For this case we have as data: 1) hypotenuse of the triangle 2) Angle between the base of the triangle and the hypotenuse. Therefore, we can use the following trigonometric relationship: [tex]sine (40) = AC / 10
[/tex] From here, we clear the value of AC. We have then: [tex]AC = 10 * sine (40)
[/tex] Answer: The encuacion that can be used to find the length of AC is given by: [tex]AC = 10 * sine (40)
[/tex] option 1
