+1495 Help me Please.
Trigonometry: Given\(\Delta ABC\) , solve for the sides or angles.
Convert 40 minutes into degrees:
40 / 60 =2/3 add this to 56 degrees:
56 2/3 =Angle A. Use the cos function:
Cos(56 2/3) = Adjacent side / Hypotenuse
Cos(56 2/3) = 22 / c Take the cos of 56 2/3 degrees.
0.5495 =22 / c Cross multiply
0.5495c = 22 Divide both sides by 0.5495
c =22 / 0.5495
c = 40.0 Feet.
