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.

One angle of a triangle measures 10 degrees more than the second. the measure of the third angle is twice the sum of the first t

Leno4ka [110]

Let x = second angle
let x + 10 = first angle
let 2( (x) + (x+10) ) = third angle.
Since the interior of a triangle equals 180° then,
$(x) + (x + 10) + 2((x) + (x + 10)) = 180$
$x + x + 10 + 2(2x + 10) = 180$
$x + x + 10 + 4x + 20 = 180$
$6x + 30 = 180$
$6x = 150$
$x = 25$
Inputting the value of x gives us each angle.

second angle = 25°
first angle = x + 10 = 25 + 10 = 35°
third angle = 2( (x) + (x+10) ) = 2( (25) + (25+10) )
= 110°
