A boat heading out to sea starts out at Point A, at a horizontal distance of 1465 feet
Pani-rosa [81]

By using what we know about right triangles, we will see that the distance is 1479.4 ft

<h3></h3><h3>How to find the distance between point A and point B?</h3>

We assume that the distance between the points is a hypotenuse of a right triangle whit one of the angles measuring 8°, and the adjacent cathetus measuring 1465 ft.

Then we use the relation:

Cos(a) = (adjacent cath)/(hypotenuse)

cos(8°) = (1465 ft)/(distance)

distance = (1465ft)/cos(8°) = 1479.4 ft

Triangle L N M is shown. Angle L N M is 90 degrees, angle N M L is 48 degrees, and angle M L N is 42 degrees. Consider △LMN. m∠L
blondinia [14]

Answer:

  • m∠L + m∠M = 90°
  • sin(L) = 0.66913
  • sin(M) = 0.74314

Step-by-step explanation:

The sum of the two angles is ...

  m∠L + m∠M = 42° +48° = 90°

__

A calculator can show you the sines of these angles.

  sin(42°) ≈ 0.66913

  sin(48°) ≈ 0.74314

_____

The two acute angles of a right triangle always have a sum of 90°.
