14.16 + 0.08(14.16) = 14.16 + 1.13 = 15.29 <==
Answer:
137.4 meters
Step-by-step explanation:
In this case, they give us the height of the lighthouse that corresponds to 50 meters and the depression angle is 20 °, in this case we can apply the tangent trigonometric function, which relates the opposite side to the adjacent side.
tan a ° = opposite / adjacent
the horizontal that is formed would be the adjacent side, therefore if we solve we are left with:
horizontal distance = opposite / tan to °
replacing, we are left with:
hd = 50 / tan 20 °
hd = 50 / 0.3639
hd = 137.4
the horizontal distance is equal to 137.4 meters
#1. 5(t+3)=-10
5t+15=-10
5t=-25
t=-5
#2. -(c-10)=0
-c+10=0
c=10
#3. -10(s+3)=-15
-10s-30=-15
-10s=15
s=-3/2
#4. 5(f-5)=-60
5f-25=-60
5f=-35
f=-7
#5. -5(2t+2)=-70
-10t-10=-70
-10t=-60
t=6
#6. 4(3w+2)/3=-6
12w+8=-18
12w=-26
w=-13/6
#7.Substitute the °C with -8
Equation:
5/9(F-32)=-8
divide both sides by 5/9
F-32= -14.4
add 32 to both sides
F=17.6
Answer: -8°C in °F is approximately 18°F.
BTW, to get the degree sign, it's option+shift+8.
