Can someone please help me

Nimfa-mama [501]

Answer:

So you must do tan(27)=x/2000
Then once you have x you do: x^2+y^2=c^2
solve for c
then add up all the sides and then subtract your total by 2000 to get the difference

A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, t

otez555 [7]

Answer:

Distance covered by the boat was 446.27 feet

Step-by-step explanation:

A boat which is at the point C approaching the light house.

At point C angle of depression to the boat was 17°44' and when boat stops at point B angle of depression was 48°13'.

Length of the tower is 200 feet then distance DC traveled by the boat.

Since at point B angle of depression was 17°44' so we will convert the angle in degrees.

Angle of depression = ∠ACB = 17°44' = $17+\frac{44}{60}=17+0.73=17.73$

From ΔABC

tan 17.73° = $\frac{200}{BC}$

$0.320=\frac{200}{BC}$

$BC=\frac{200}{0.32}= 625 feet$

Now in ΔABD

∠ADB = 48°13' = 48° + $\frac{13}{60}=48 + 0.217$ = 48.217°

Now $tan(48.217)=\frac{200}{BD}$

$BD=\frac{200}{1.119}=178.73 feet$

Therefore distance DC = BC - BD

DC = 625 - 178.73 = 446.27 feet

So the answer is 446.27 feet was distance covered by the boat.

Find the slope of the given line on the graph. REMEMBER: Rise over run! <br> Pls show work!

Leviafan [203]

Answer:

the slope is $-\frac{1}{3}$

Step-by-step explanation:

Notice that you are given two points to use for the slope calculation:

$(x_1,y_1)=(-4,4) \,\,and\,\, (x_2,y_2)=(5,1)$

So we use the formula for the slope of a line given two points:

$slope\,=\,\frac{y_2-y_1}{x_2-x_1} \\slope\,=\,\frac{1-4}{5-(-4)} \\slope\,=\,\frac{-3}{9} \\slope\,=\,-\frac{1}{3} \\$
