Ответ:
3/4
Step-by-step explanation:
sin = opposite/hypotenuse
one side is 3, hypotenuse side is 5.
using the pythagorean theorem, we know that the third side is 4.
tan = opposite/adjacent
tanθ = 3/4
Ответ:
Let's assume CD=h, BD=x.
tan 24°=h/x ==>h=x*tan 24°
tan 16°=h/(7600+x)==>h=tan 16° *(7600+x)
==>x tan 24°=tan 16°*(7600+x)
==>x=(7600*tan 16°)/(tan 24°-tan 16°)
h=x*tan 24= (7600*tan 16°*tan 24°)/(tan 24°-tan16°)
b) CD=h=6122,2303...≈6122 (feet)
a) BC=h/sin 24°=15052,0746448...≈15052 (feet)
